A very simple overview is that you call vstr_init() at the start
of your program and vstr_exit() at the end.
You can make new Vstr strings by calling vstr_make_base(), and free them by
calling vstr_free_base(). There are also a vstr_dup_* set of functions to
make a new Vstr string with data in them.
You can then add/delete data from this string, using the provided functions,
if you need to use all or part of the string with a "C string"
interface then you can call vstr_export_cstr_ptr() or
vstr_export_cstr_malloc().
Function: vstr_init()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Nothing
Type[1]: void
Explanation:
This function needs to be called before any of the other functions are
called.
Note:
The function can be called multiple times, without any problems.
Function: vstr_exit()
Returns: Nothing
Type: void
Parameter[1]: Nothing
Type[1]: void
Explanation:
This function can be called before exit, after all vstr objects have been
freed, to cleanup data allocated internally in the Vstr library.
Note:
The function isn't needed but helps make sure there are no memory leaks, when
used with a memory checker (or with the internal memory checker in the debug
build).
Function: vstr_export_cstr_ptr()
Returns: A pointer to an array of characters, terminated by NIL
Type: const char *
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Start position in the Vstr
Type[2]: size_t
Parameter[3]: Length from position in the Vstr
Type[3]: size_t
Explanation:
This function is used to export a pointer to an array of characters of length
(Parameter[3] + 1), the last byte will be a 0 to terminate the "C
string".
Multiple adjacent calls will return the same pointer.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return NULL if it needs to allocate memory and cannot do
so.
Note:
If you alter the Vstr in anyway then the returned pointer may point to
free()'d memory. To get a reference to this data use vstr_export_cstr_ref()
instead.
This data needs to be cached in the Vstr string, and so can only work if the
Vstr string has the ability to cache data (see
VSTR_CNTL_BASE_GET_FLAG_HAVE_CACHE). If you want to make sure that the
cached data is gone from the Vstr string, cache then you can call
vstr_cache_cb_free() on the cookie from "/vstr__/cstr".
Any _NON data in the Vstr will be uninitialized data in the "C
string".
If there are any 0 bytes in the Vstr they will make the string look shorter
than it really is to normal C style string functions.
Function: vstr_export_cstr_malloc()
Returns: A malloc'd pointer to an array of characters, terminated by NIL
Type: char *
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Start position in the Vstr
Type[2]: size_t
Parameter[3]: Length from position in the Vstr
Type[3]: size_t
Explanation:
This function is used to export a malloc'd pointer to an array of characters
of length (Parameter[3] + 1), the last byte will be a 0 to terminate the
"C string". You will need to pass the pointer to free(), when you
are done with it.
Each call will return a different pointer.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return NULL if it needs to allocate memory and cannot do
so.
Note:
Any _NON data in the Vstr will be uninitialized data in the "C
string".
If there are any 0 bytes in the Vstr they will make the string look shorter
than it really is to normal C/POSIX string functions.
Function: vstr_export_cstr_buf()
Returns: Nothing
Type: void
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Start position in the Vstr
Type[2]: size_t
Parameter[3]: Length from position in the Vstr
Type[3]: size_t
Parameter[4]: Data array to export to
Type[4]: void *
Parameter[5]: Length of data (Parameter[4])
Type[5]: size_t
Explanation:
This function is used to export a copy of the data in the Vstr string to a
data array, the maximum amount of data stored in the array will be of length
(Parameter[3] + 1), the last byte will be a 0 to terminate the "C
string". However the data before the terminator of the "C
string" is limited to (Parameter[5] - 1).
Note:
Data from nodes of type NON are exported by not doing anything to the
underlying data array (Ie. It'll have whatever data was in there to start
with).
If there are any 0 bytes in the Vstr they will make the "C string"
look shorter than it really is to normal C/POSIX string functions.
Function: vstr_export_cstr_ref()
Returns: Vstr memory reference
Type: struct Vstr_ref *
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Start position in the Vstr
Type[2]: size_t
Parameter[3]: Length from position in the Vstr
Type[3]: size_t
Parameter[4]: Offset of Vstr memory reference (Return)
Type[4]: size_t *
Explanation:
This function is used to return a pointer to a Vstr memory reference of at
least length (Parameter[3] + 1), the last byte will be a 0 to terminate the
"C string" stored in (Vstr_ref *)->ptr. The offset
(Parameter[4]) should be used to find the beginning of the block of memory
to use.
When you are finished with the reference you need to use vstr_ref_del() or
the memory will stay allocated forever.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return NULL if it needs to allocate memory and cannot do
so.
Note:
If you want to make sure that the cached data is gone from the Vstr string,
cache then you can call vstr_cache_cb_free() on the cookie from
"/vstr__/cstr".
Any _NON data in the Vstr will be uninitialized data in the "C
string".
If there are any 0 bytes in the Vstr they will make the string look shorter
than it really is to normal C/POSIX string functions.
Function: vstr_export_iovec_ptr_all()
Returns: Size of bytes in the Vstr string
Type: size_t
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Returns the start of the iovec array
Type[2]: struct iovec **
Parameter[2]: Returns the number of iovec structures in the
array
Type[2]: unsigned int *
Explanation:
This function is used to export a pointer to an array of iovec structures
this can then be passed directly to writev() etc. or just used to quickly
access the data in the Vstr string.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return 0 if it needs to allocate memory and cannot do
so.
Note:
Nodes of type NON are represented by a iov_base set to NULL.
Altering the iov_base/iov_len members will probably do very bad things, if
you need to do this use the vstr_export_iovec_cpy_ptr()
Altering the data in the iovec structure isn't a good idea as it isn't easy
for the programer to know if the data is shared/read-only. If you need to do
this you should use either the vstr_sub_* functions instead or
vstr_export_iovec_cpy_buf() (the later does a copy). However if you do alter
the data then you'll need to do vstr_cache_cb_sub().
Either of the pointers for the iovec array (Parameter[2]) or the number of
iovecs (Parameter[3]) can be the NULL pointer, in which case nothing will be
written to those pointers.
Function: vstr_export_iovec_cpy_buf()
Returns: Size of bytes exported from the Vstr string
Type: size_t
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *

Parameter[3]: Length in the Vstr string (Parameter[1])
Type[3]: size_t
Parameter[4]: Pointer to array of initialized iovec
structures
Type[4]: struct iovec *
Parameter[5]: Number of iovec structures (Parameter[4])
Type[5]: unsigned int
Parameter[6]: Returns the number of iovec structures used
in the array
Type[6]: unsigned int *
Explanation:
This function is used to export a copy of the data in the Vstr string to an
array of iovec structures this can then be passed directly to writev() (or
even a readv() although that wouldn't often be useful) etc.
Think of this function as doing a readv() from a Vstr string.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
Note:
Data from nodes of type NON are exported by not doing anything to the
underlying iov_base data arrays (Ie. It'll have whatever data was in there
to start with).
The length returned may be shorter than that given as Parameter[3], as it's
the number of bytes copied into the iov_base arrays in the iovec
structures.
Function: vstr_export_iovec_cpy_ptr()
Returns: Size of bytes exported from the Vstr string
Type: size_t
Parameter[1]: Vstr string

Parameter[2]: Start position in the Vstr string
(Parameter[1])
Type[2]: size_t
Parameter[3]: Length in the Vstr string (Parameter[1])
Type[3]: size_t
Parameter[4]: Pointer to array of iovec structures
Type[4]: struct iovec *
Parameter[5]: Number of iovec structures (Parameter[4])
Type[5]: unsigned int
Parameter[6]: Returns the number of iovec structures used
in the array
Type[6]: unsigned int *
Explanation:
This function is used to export a set of pointer/length pairs to the data
specified in the Vstr string, this can then be passed directly to writev()
etc.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
Note:
Nodes of type NON are represented by a iov_base set to NULL.
Altering the data in the iovec structure isn't a good idea as it isn't easy
for the programer to know if the data is shared/read-only. If you need to do
this you should use either the vstr_sub_* functions instead or
vstr_export_iovec_cpy_buf() (the later does a copy).
Function: vstr_export_buf()
Returns: Size of bytes exported from the Vstr string
Type: size_t
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Start position in the Vstr string
(Parameter[1])
Type[2]: size_t
Parameter[3]: Length in the Vstr string (Parameter[1])
Type[3]: size_t
Parameter[4]: Data array to export to
Type[4]: void *
Parameter[5]: Length of data (Parameter[4])
Type[5]: size_t
Explanation:
This function is used to export a copy of the data in the Vstr string to a
data array.
Think of this function as doing a read() from a Vstr string. However the data
will be limited to the minimum of the length of the vstr (Parameter[3]) and
the length of the data (Parameter[5]).
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
Note:
Data from nodes of type NON are exported by not doing anything to the
underlying data array (Ie. It'll have whatever data was in there to start
with).
Function: vstr_export_chr()
Returns: Character exported from the Vstr string
Type: char
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Position in the Vstr string (Parameter[1])
Type[2]: size_t
Explanation:
This function is used to return a character at a certain position in a Vstr
string.
Note:
It is impossible to distinguish between an error, data from a NON node and
real data that is equal to the value 0.
Function: vstr_export_ref()
Returns: Vstr memory reference
Type: struct Vstr_ref *
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Start position in the Vstr
Type[2]: size_t
Parameter[3]: Length from position in the Vstr
Type[3]: size_t
Parameter[4]: Offset of Vstr memory reference (Return)
Type[4]: size_t *
Explanation:
This function is used to return a pointer to a Vstr memory reference of at
least length (Parameter[3]). The offset (Parameter[4]) should be used to
find the beginning of the block of memory to use.
When you are finished with the reference you need to use vstr_ref_del() or
the memory will stay allocated forever.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return NULL if it needs to allocate memory and cannot do
so.
Note:
Any _NON data in the Vstr will be uninitialized data in the memory pointed to
by the memory reference.

Function: vstr_ref_cb_free_ptr()
Returns: Nothing
Type: void
Parameter[1]: Vstr memory reference
Type[1]: struct Vstr_ref *
Explanation:
This will call free() on the data in the Vstr_ref (Parameter[1])->ptr
(unless the passed reference is the NULL pointer, then it does nothing).
Function: vstr_ref_cb_free_ptr_ref()
Returns: Nothing
Type: void
Parameter[1]: Vstr memory reference
Type[1]: struct Vstr_ref *
Explanation:
This will call free() on the data in the Vstr_ref (Parameter[1])->ptr and
then call free() on the Vstr_ref (Parameter[1]) (unless the passed reference
is the NULL pointer, then it does nothing).
Function: vstr_ref_make_malloc()
Returns: Vstr memory reference
Type: struct Vstr_ref *
Parameter[1]: Size of malloc'd area to create in the memory
reference
Type[1]: size_t
Explanation:
This function will create an area of memory, using malloc, and create a Vstr
memory reference to that memory. The Vstr memory reference will have a

free both the reference and the copy of memory.
Function: vstr_ref_make_ptr()
Returns: Vstr memory reference
Type: struct Vstr_ref *
Parameter[1]: Pointer to memory
Type[1]: void *

Returns: Vstr memory reference
Type: struct Vstr_ref *
Parameter[1]: Pointer to memory
Type[1]: void *
Parameter[2]: Length of memory block
Type[2]: size_t
Explanation:
This function will create a Vstr memory reference. The Vstr memory reference
will have a reference count of 1 and a copy of the memory pointed to by
(Parameter[1]) of length (Parameter[2]) will be the pointer value. The
cleanup function will point to a function to free both the reference and the
copy of memory.
Function: vstr_ref_make_strdup()
Returns: Vstr memory reference
Type: struct Vstr_ref *
Parameter[1]: Pointer to data

Explanation:
This function is used to add a copy of the data in the data array to a Vstr
string.
Think of this function as doing a write() into a Vstr string.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return 0 if it needs to allocate memory and cannot do so,

although if it does fail the Vstr string won't have changed (Ie. the
function is atomic).
Note:
If the data in the array needs to be free'd the programer will have to decide
when it is no longer being used by the Vstr string and free it. It is often
easier to create a memory reference and use vstr_add_ref() instead.

Explanation:
This function is used to add data in one Vstr string (Parameter[3]) to
another Vstr string (Parameter[1]).
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return 0 if it needs to allocate memory and cannot do so,
although if it does fail the Vstr string won't have changed (Ie. the
function is atomic).
Note:
The function can change how the data is added to the Vstr string
(Parameter[1]) and in some cases even how the data is represented in the
Vstr string (Parameter[3]) for more information see the documentation on the
VSTR_TYPE_ADD_* constants.
This function will set _both_ (Parameter[1])->conf->malloc_bad and
(Parameter[3])->conf->malloc_bad if any of the allocation calls
fails.

Type[2]: size_t
Parameter[3]: Format string, a superset of the rules for
C99 printf
Type[3]: const char *
Parameter[4]: Standard argument object from va_start()
Type[4]: va_list
Explanation:
This function works like calling vsprintf() directly into a Vstr string,
however this is a portable implementation which is feature complete with
glibc-2.2.x sprintf(); implements custom specifiers, if you use the
vstr_fmt_add() function, and doesn't require a double copy.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return 0 if it needs to allocate memory and cannot do so,
although if it does fail the Vstr string won't have changed (Ie. the
function is atomic).
Note:
Depending on how the library was compiled double support is implemented by
either calling the underlying host implementation of sprintf(), by internal
code or simply by assuming all double's are zero. When using the host
implementation system bugs of inaccuracy will show through, however the
feature set remains the same (Ie. the ' flag works the same).
Because specifiers can be overridden using vstr_fmt_add() if you are adding
data to a Vstr string that you didn't create you should use either
vstr_add_vsysfmt() or vstr_swap_conf().
Function: vstr_add_fmt()
Returns: Number of bytes added
Type: size_t
Parameter[1]: Vstr string
Type[1]: struct Vstr_base *
Parameter[2]: Append position in the Vstr string

Parameter[3]: Format string, a superset of the rules for
C99 printf
Type[3]: const char *

specifiers (see vstr_fmt_add()).
Function: vstr_add_sysfmt()
Returns: Number of bytes added
Type: size_t
Parameter[1]: Vstr string
Type[1]: struct Vstr_base *
Parameter[2]: Append position in the Vstr string

Explanation:

(Parameter[4]) a va_list object.
Function: vstr_add_iovec_buf_beg()
Returns: Number of bytes in the iovec array
Type: size_t
Parameter[1]: Vstr string
Type[1]: struct Vstr_base *
Parameter[2]: Append position in the Vstr string
(Parameter[1])
Type[2]: size_t
Parameter[3]: Minimum amount of iovecs to add
Type[3]: unsigned int
Parameter[4]: Maximum amount of iovecs to add
Type[4]: unsigned int
Parameter[5]: Returns the start of the iovec array
Type[5]: struct iovec **
Parameter[6]: Returns the number of iovec structures in the
array
Type[6]: unsigned int *
Explanation:
This function is used to add a copy of data directly into the Vstr string,
the amount of data available will be between the minimum (Parameter[4]) and
maximum ((Parameter[5]) + 1) number of iovecs multiplied by the length of
data in _BUF type nodes. The obvious use for the data is to call readv() on
it.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return 0 if it needs to allocate memory and cannot do so,
although if it does fail the Vstr string won't have changed (Ie. the
function is atomic).
Note:
You shouldn't call any other vstr functions between vstr_add_iovec_buf_beg()
and vstr_add_iovec_buf_end(), unless you know that they are operating on a
different Vstr string which is using a different Vstr configuration.
The reason there is a +1 on the maximum value is that data may be appended to
a _BUF node just before the start of where the data is to go, this is almost
guaranteed to happen when adding to the end of a Vstr string and saves a lot
of wasted space.
It is currently believed that, on Linux, doing disk IO in amounts greater
than 8k gives little real performance improvement. This can be converted
into iovec numbers by using a formula like...
min = (8k / buf_sz) + 2;
max = min + (min / 2);
...where the +2 is due to both the extra space at the end of the current last
node, and rounding errors due to the division. The max being slightly bigger
is an attempt to make the constant overhead of the call slightly less, and
may not be useful. It is very possible that some kind of dynamic scaling of
the values would result in the best performance, however the solution to
that doesn't fit in the margin :).
Function: vstr_add_iovec_buf_end()
Returns: Nothing
Type: void
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Append position in the Vstr string
(Parameter[1])
Type[2]: size_t
Parameter[3]: Number of bytes added to the iovec array
Type[3]: size_t
Explanation:
This function is used after calling vstr_add_iovec_buf_beg() and you've then
filled in a bunch of data.
Note:
Although it's safe to not bother calling this function if you didn't have
anything to add to the Vstr string it is often more efficient to call this
function with Parameter[3] as 0.
Function: vstr_add_netstr_beg()
Returns: Position of start of netstr (Parameter[2]) + 1
Type: size_t
Parameter[1]: Vstr string
Type[1]: struct Vstr_base *
Parameter[2]: Append position in the Vstr string
(Parameter[1])
Type[2]: size_t
Explanation:
This function creates the start of a netstring
http://cr.yp.to/proto/netstrings.txt this can be used in conjunction with
vstr_add_netstr_end() to easily create netstrings.
Function: vstr_add_netstr_end()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr string
Type[1]: struct Vstr_base *
Parameter[2]: Position returned from vstr_add_netstr_beg()
Type[2]: size_t
Parameter[3]: End of netstring
Type[3]: size_t
Explanation:
This function is called after calling vstr_add_netstr_beg(), adding all the
data you want to the netstring and then passing the position of the end of
that data.
Upon success a valid netstring will contain all the data added between the
two calls.
Note:
It is valid to pass the same values for (Parameter[2]) and (parameter[3]), as
that signifies that there is no data in the netstring.
It is almost guaranteed that data will need to be removed from the beginning
of the netstring due to the length being shorter than the maximum, this is
inefficient and could cause problems if you know how big the Vstr string is
you can use the vstr_add_netstr2_* functions to solve both problems.
Function: vstr_add_netstr2_beg()
Returns: Position of start of netstr (Parameter[2]) + 1
Type: size_t
Parameter[1]: Vstr string
Type[1]: struct Vstr_base *
Parameter[2]: Append position in the Vstr string
(Parameter[1])
Type[2]: size_t
Explanation:
This function creates the start of a netstring2 which is like a netstring
http://cr.yp.to/proto/netstrings.txt but can have leading zeros, this can be
used in conjunction with vstr_add_netstr2_end() to easily create
netstring2s.
Function: vstr_add_netstr2_end()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr string
Type[1]: struct Vstr_base *
Parameter[2]: Position returned from vstr_add_netstr2_beg()
Type[2]: size_t
Parameter[3]: End of netstring2
Type[3]: size_t
Explanation:
This function is called after calling vstr_add_netstr2_beg(), adding all the
data you want to the netstring2 and then passing the position of the end of
that data.
Upon success a netstring2 will contain all the data added between the two
calls.
Note:
It is valid to pass the same values for (Parameter[2]) and (parameter[3]), as
that signifies that there is no data in the netstring.
No data is ever removed from the beginning of a netstring2, this is
incompatible with the netstring spec. but is more efficient and doesn't
cause problems if you know how big the Vstr string is and can't have it lose
data from the beginning/middle.
Function: vstr_del()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr string
Type[1]: struct Vstr_base *
Parameter[2]: Start position in the Vstr string
(Parameter[1])
Type[2]: size_t
Parameter[3]: Length in the Vstr string (Parameter[1])
Type[3]: size_t
Explanation:
This function is used to delete data in the Vstr string.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return 0 if it needs to allocate memory and cannot do so,
although if it does fail the Vstr string won't have changed (Ie. the
function is atomic).
Note:
Deleted nodes do not get returned to the system, they get put into a pool in
the Vstr configuration for reuse on the next call to a vstr_add_*()
function.
Deleting the entire Vstr string and deleting from the beginning onward are
faster operations than a generic delete. They also never require allocating
memory and so the return value can be ignored.
Function: vstr_mov()

(Parameter[3]) and adding it to another Vstr string (Parameter[1]).
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return 0 if it needs to allocate memory and cannot do so,
although if it does fail the Vstr string won't have changed (Ie. the

Explanation:
This function is used to substitute the data in the Vstr string with a copy
of the data in the data array.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
The function will return 0 if it needs to allocate memory and cannot do so,
although if it does fail the Vstr string won't have changed (Ie. the

the length of the data (Parameter[5]).
Think of this function as doing a vstr_del() and then a vstr_add_buf() (but
it's atomic).
If the length of the data (Parameter[5]) is less than or equal to the length
of the Vstr string (Parameter[3]) and the data in the Vstr string is in a
BUF node then the data will just be overwritten (Ie. no allocations will
happen).

Type[6]: size_t
Explanation:
This function is used to compare the data in one Vstr string (Parameter[1])
with data in another Vstr string (Parameter[4]), however for ASCII digits
the algorithm tests on the numbers themselves (so "10" is greater
than "9" but "01" is greater than "012", as
the later are fractions).
Think of this function as doing a vstr_export_cstr_ptr() on each Vstr string,
and then a call to strverscmp() (although it doesn't allocate anything,
_and_ it deals with 0 bytes in the data).
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.

Data of type _NON is assumed to have the value -1, and so all data compares
as greater than it.

Type[3]: int (*)(struct Vstr_base *, size_t, struct Vstr_fmt_spec
*)
Parameter[4]: List of VSTR_TYPE_FMT_* types for format
specifier (Parameter[2])
Type[4]: ...
Explanation:
This function allows you to register arbitrary format specifiers for printing
from vstr_add_fmt(). Note that these trigger off the user escape character,
which may or may not be the same as the "system" escape character
of '%'.
The call back you register should return 0 (zero) if memory couldn't be
allocated and 1 (one) otherwise.
Note:
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
If the user escape character is '%', then you can override system specifiers
by using a specifier name (Parameter[2]) of "i" etc. This isn't
recommended, but is done so that you can have specifier names like
"igloo" and it not be taken as a system specifier, however if you
then did "%igoo" that would be interpreted as a "%i"
(int) specification followed by the string "goo".
You can register multiple names with one callback, so you can register say
"{Vstr}" and "{Vstr:%p%zu%zu%u}" ... the latter, with a
user escape != '%', will do the right thing with current printf warning
checks in gcc. We can all hope that the former will be as usable eventually.
If you register all your custom formatter names starting with one of
"{", "[", "<" or "(" and ending
with one of "}", "]", ">" or ")"
and no other instances of those characters ... then matching custom
formatters will be much faster.

Function: vstr_sc_fmt_add_all()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr configuration
Type[1]: struct Vstr_conf *
Explanation:
This function is a shortcut to adding a custom formatter for each of the
specific custom formatters. The names used are as those given in the notes
section of each custom formatter. Also 4 alternate names are given so that
the formatter can be used in a gcc warning compatible way. For instance the
vstr_add_buf() formatter is "{buf}", however the names
"{buf:%s%zu}", "{buf:%*s%zu}",
"{buf:%.*s%zu}", "{buf:%*.*s%zu}",
"{buf:%d%s%zu}" and "{buf:%d%d%s%zu}" are also added
(the later two are slightly less readable, but required for custom formaters
whos first argument is a %p.
Note:
The function will return 0 if it needs to allocate memory and cannot do so.
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
If any of the custom formatter adds fails (for example, if the name is
already in use) then all the rest of the names of that type will fail,
however the other remaining types of formatters will be tried.
Function: VSTR_SC_FMT_ADD()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr configuration
Type[1]: struct Vstr_conf *
Parameter[2]: Function to add the custom formatter ability
Type[2]: int (*)(struct Vstr_conf *, const char *)
Parameter[3]: Prefix string
Type[3]: const char *
Parameter[4]: Static format check string, without the
leading % sign
Type[4]: const char *
Parameter[5]: Postfix string
Type[5]: const char *
Explanation:
This macro function calls the function to add the custom formatting ability
(Parameter[2]), with the Vstr configuration (Parameter[1]) and a string
composed of the values from prefix, and the postfix. It then calls the
function with the prefix, various middle strings with the static format
check string, and the postfix. For example the following call...
VSTR_SC_FMT_ADD(NULL, func, "<foo", "p",
">");
...will register the format "<foo>", but also the formats
"<foo:%p>",
"<foo:%p>", "<foo:%*p>",
"<foo:%.*p>", "<foo:%*.*p>",
"<foo:%d%p>" and "<foo:%d%d%p>". This is all
that is required to fool static format string checkers, even when you are
passing formating information in parameters.
Note:
No cleanup is done on failure, so if the second registration fails then the
first custom formatter will still be registered on return.
Function: vstr_sc_mmap_fd()
Returns: TRUE on success and FALSE on failure

Explanation:
This function is used to add a mmap()d mapping of data from a file descriptor
(Parameter[3]) at offset (Parameter[4]) and of size (Parameter[5]) to a Vstr
string.
Note:
If the size (Parameter[5]) is zero, then then the size of the file is
automatically worked out and the size (Parameter[5]) becomes the file size
minus the offset (Parameter[4]).
Function: vstr_sc_mmap_file()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr string

VSTR_TYPE_SC_READ_FD_ERR_
Type[6]: unsigned int *
Explanation:
This function is used to call vstr_add_iovec_buf_beg(), then readv() with the

Type[3]: int
Parameter[4]: Size of data to try to read
Type[4]: size_t

Explanation:
This function is used to call vstr_add_iovec_buf_beg(), then readv() with the
file descriptor (Parameter[3]) and finally vstr_add_iovec_buf_end() before
returning.
However the arguments to the vstr_add_iovec_buf_* calls are limited so that
only up to size (Parameter[4]) data will be read.
If size (Parameter[4]) is zero then the entire file will try to be read.
Note:
As with all calls in the vstr library, this is a non-blocking call. If you
need all of the data specified (Parameter[4]) then you'll need to loop.

Parameter[7]: Returns error code starting
VSTR_TYPE_SC_READ_FILE_ERR_
Type[7]: unsigned int *
Explanation:
This function is used to call vstr_add_iovec_buf_beg(), then readv() with the
file descriptor got by opening the filename (Parameter[3]) and finally
vstr_add_iovec_buf_end() before returning.
However the arguments to the vstr_add_iovec_buf_* calls are limited so that
only up to size (Parameter[4]) data will be read.
However the arguments to the vstr_add_iovec_buf_* calls are limited so that
only up to exactly size (Parameter[4]) data will be read. If size
(Parameter[5]) is zero then the entire file, minus the offset (Parameter[4])
will try and be read.
Note:
If all the data is read() and then close() fails with an error, although the
error code will signify this the data will stay inside the Vstr as this
seemed the most useful/sane behaviour.
read() is called multiple times from this function, so it should return after
either all the data has been read from the file into the Vstr or an error
has occured.

Parameter[4]: Returns error code starting
VSTR_TYPE_SC_WRITE_FD_ERR_
Type[4]: unsigned int *
Explanation:
This function is used to take data from a Vstr string and write it to a file
descriptor. Specifically this means that after the call any data written
will be removed from the Vstr (Parameter[1]), making write analogous to read
which fills in the data.
Note:
If the start position is 1, the length is (Parameter[1])->len and caching
is available for the Vstr string the data will be exported as though
vstr_export_iovec_ptr_all(), writev() and then vstr_del() were called.

Parameter[7]: Offset to start writing at
Type[7]: off64_t
Parameter[8]: Returns error code starting
VSTR_TYPE_SC_WRITE_FILE_ERR_
Type[8]: unsigned int *
Explanation:
This function is used to take data from a Vstr string and write it to a file,
after open()ing the file (Parameter[4]) with open flags (Parameter[5]) and
open mode (Parameter[6]).
Note:
Because multiple system calls will be done inside this function, and that
doing a write automatically removes data it's possible for this function to
return failure but have actually written some data out. The other
alternative would be to copy all the data until after the close() happened,
which would be vastly less efficient.

Explanation:
This function is used to initialized an iteration.
Note:
The only time this function will return FALSE is if you pass an invalid
position and length.
If you alter the Vstr string (Parameter[1]) while using a iteration, then the
iteration will be in an undefined state.
Function: vstr_iter_fwd_nxt()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr iteration
Type[1]: struct Vstr_iter *
Explanation:
This function is used to step to the next iteration.
Note:
If you alter the Vstr string (Parameter[1]) while using a iteration, then the
iteration will be in an undefined state.
Function: vstr_iter_fwd_chr()
Returns: Character at that point in iteration
Type: char
Parameter[1]: Vstr iteration
Type[1]: struct Vstr_iter *
Parameter[2]: Vstr iteration return type
(VSTR_TYPE_ITER_*).
Type[2]: unsigned int *
Explanation:
This function is used to return the current character and post increment the
iteration (Ie think "ret = *iter++"). However it is safe to call
vstr_iter_fwd_chr() forever, after it gets to the end of the iteration it
will just return 0 (and set the return type to _END).
Note:
If you alter the Vstr string (Parameter[1]) while using a iteration, then the
iteration will be in an undefined state.
Function: vstr_iter_fwd_buf()
Returns: Length of iteration moved
Type: size_t
Parameter[1]: Vstr iteration
Type[1]: struct Vstr_iter *
Parameter[2]: Length to move iteration forward
(Parameter[1])
Type[2]: size_t
Parameter[3]: Data array to export to
Type[3]: void *
Parameter[4]: Length of data (Parameter[3])
Type[4]: size_t
Parameter[5]: Vstr iteration return type
(VSTR_TYPE_ITER_*).
Type[5]: unsigned int *
Explanation:
This function is used to move the iteration forward a particular length
(Parameter[2]). It will also export the data for the length, if there is
room.
It is safe to call vstr_iter_fwd_buf() forever, after it gets to the end of
the iteration it will just return 0 (and set the return type to _END). If
the passed length is greater than the length of the iteration left, the
length will be truncated and the truncated value will be returned.
Passing NULL as the buffer (Parameter[3]) is only valid if the buffer length
(Parameter[4]) is zero.
Note:
If you alter the Vstr string (Parameter[1]) while using a iteration, then the
iteration will be in an undefined state.
Function: vstr_iter_fwd_cstr()
Returns: Length of iteration moved
Type: size_t
Parameter[1]: Vstr iteration
Type[1]: struct Vstr_iter *
Parameter[2]: Length to move iteration forward
(Parameter[1])
Type[2]: size_t
Parameter[3]: Data array to export to
Type[3]: char *
Parameter[4]: Length of data (Parameter[3])
Type[4]: size_t
Parameter[5]: Vstr iteration return type
(VSTR_TYPE_ITER_*).
Type[5]: unsigned int *
Explanation:
This function works like vstr_iter_fwd_buf(), except that the buffer
(Parameter[3]) must be non-NULL and the end of the data exported using the
iteration will always be NIL terminated.
Function: vstr_iter_pos()
Returns: Position of iteration
Type: size_t
Parameter[1]: Vstr iteration
Type[1]: struct Vstr_iter *
Parameter[2]: Start position in the Vstr string
(Parameter[1])
Type[2]: size_t
Parameter[3]: Length in the Vstr string (Parameter[1])
Type[3]: size_t
Explanation:
This function is used to return the current position in the iteration.
Function: vstr_iter_len()
Returns: Length of iteration
Type: size_t
Parameter[1]: Vstr iteration
Type[1]: struct Vstr_iter *
Explanation:
This function is used to return the length remaining of the iteration.
Function: vstr_cntl_opt()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Option type starting VSTR_CNTL_OPT_*
Type[1]: int
Parameter[ ... ]: Options depending on value of
Parameter[1]
Type[ ... ]: ...
Explanation:
This function will get or set global options.
Function: vstr_cntl_base()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Option type starting VSTR_CNTL_BASE_*
Type[2]: int
Parameter[ ... ]: Options depending on value of
Parameter[2]
Type[ ... ]: ...
Explanation:
This function will get or set options for the Vstr string (Parameter[1]).
Function: vstr_cntl_conf()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]:.br Type[1]: struct Vstr_conf *
Parameter[2]: Option type starting VSTR_CNTL_CONF_*
Type[2]: int
Parameter[ ... ]: Options depending on value of
Parameter[2]
Type[ ... ]: ...
Explanation:
This function will get or set options for the Vstr configuration
(Parameter[1]).
Note:
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
Function: VSTR_FLAGXX()
Returns: The value of the flags combined
Type: unsigned int
Parameter[1]: Name of flag type to use.
Type[1]: <symbol>
Parameter[ ... ]: Names of a flags in the given flag type
Type[ ... ]: <symbol>
Explanation:
This isn't one macro function but a group of functions that all do the same
thing, just with different numbers of arguments. They combine the namespace
requirements so that you can specify multiple flags in a concise manner. For
instance VSTR_FLAG06() combines 6 flags. So instead of having to wite...
(VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_NUL |
VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_BEL |
VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_BS |
VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_HT |
VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_LF |
VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_VT)
...you can write...
VSTR_FLAG06(CONV_UNPRINTABLE_ALLOW, NUL, BEL, BS, HT, LF, VT)
...which is a lot more readable as the number of flags increases.
The Range of macro functions is from VSTR_FLAG01() to VSTR_FLAG31(), the
number at the end referring to how many flags are passed to it (not the
number of parameters, which is one more than that).
Function: vstr_num()
Returns: Number of nodes used in the vstr
Type: unsigned int
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Start position in the Vstr string
(Parameter[1])
Type[2]: size_t
Parameter[3]: Length in the Vstr string (Parameter[1])
Type[3]: size_t
Explanation:
This function is used to find out how many nodes are being used for a given
section of a vstr.
If the function can detect that the values of parameters are in error the
function will return 0 to indicate an error.
Function: vstr_cache_add()
Returns: Cookie reference for cache function
Type: unsigned int
Parameter[1]: Vstr configuration
Type[1]: struct Vstr_conf *
Parameter[2]: Name of cache function
Type[2]: const char *
Parameter[3]: Function to use as callback from the cache
Type[3]: void *(*)(const struct Vstr_base *, size_t, size_t, unsigned
int, void *)
Explanation:
This function will add the callback function (Parameter[3]) to the Vstr
configuration for use in all Vstr strings that use the Vstr configuration
and have a cache. The name of the cache function (Parameter[2]) should be
unique, the vstr library uses names starting "/vstr__/".
Note:
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
The name of the cache function should be placed in permanent storage, Ie.
only the pointer to the name will be stored so you cannot malloc() the name
and then free() it after calling the function.
The callback function parameters, are the Vstr string, position, length, the
type of callback starting VSTR_TYPE_CACHE_ and the data for the cache
function.
The callback function will not be called if the data for the cache function
is NULL.
The inline adding and delete from the Vstr strings is not performed if
callbacks are registered for the string (because functions will have to be
called anyway).
Function: vstr_cache_get()
Returns: Data for cache function
Type: void *
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Cookie reference for cache function
Type[2]: unsigned int
Explanation:
This function will get the data for the cache function.
Function: vstr_cache_set()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Cookie reference for cache function
Type[2]: unsigned int
Parameter[3]: Data for cache function
Type[3]: void *
Explanation:
This function will set the data for the cache function.
Note:
The callback function will not be called if the data for the cache function
is NULL.
Function: vstr_cache_srch()
Returns: Cookie reference for cache functions
Type: unsigned int
Parameter[1]: Vstr configuration
Type[1]: struct Vstr_conf *
Parameter[2]: Name of cache function
Type[2]: const char *
Explanation:
This function will find a cache function name (Parameter[2]) and return the
cookie reference for use in the other cache functions.
Note:
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
Function: vstr_cache_cb_sub()
Returns: Nothing
Type: void
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Start position in the Vstr string
(Parameter[1])
Type[2]: size_t
Parameter[3]: Length in the Vstr string (Parameter[1])
Type[3]: size_t
Explanation:
If you are substituting data in a vstr (from an iovec export, followed by a
readv for instance or changing the data in a mmap()'d area) then you can use
this function to notify the vstr caching mechanisms.
Note:
This is a last resort function, to make the hard things possible, use the
vstr_sub_*() functions instead.
Function: vstr_cache_cb_free()
Returns: Nothing
Type: void
Parameter[1]: Vstr string
Type[1]: const struct Vstr_base *
Parameter[2]: Cookie reference for cache function
Type[2]: unsigned int
Explanation:
If you have generated cache data, this function will tell the cache function
to free that data.
Note:
A Cookie reference of "zero" means tell all cache functions to free
cached data. Note that this can cause severe performance degradation if
overly used.
Function: vstr_data_add()
Returns: Cookie reference for cache function
Type: unsigned int
Parameter[1]: Vstr configuration
Type[1]: struct Vstr_conf *
Parameter[2]: Name of cache function
Type[2]: const char *
Parameter[3]: Reference to data to store in the
configuration
Type[3]: struct Vstr_ref *
Explanation:
This function will add the data reference (Parameter[3]) to the Vstr
configuration. The name of the data reference (Parameter[2]) should be
unique, the vstr library will use names starting "/vstr__/".
Note:
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
The name of the cache function should be placed in permanent storage, Ie.
only the pointer to the name will be stored so you cannot malloc() the name
and then free() it after calling the function (you can free it after calling
vstr_data_del()).
Storing a reference that is NULL is valid, and will act like storing a
reference to NULL.
Function: vstr_data_srch()
Returns: Cookie reference for data configuration functions
Type: unsigned int
Parameter[1]: Vstr configuration
Type[1]: struct Vstr_conf *
Parameter[2]: Name of data configuration function
Type[2]: const char *
Explanation:
This function will find a configuration data name (Parameter[2]) and return
the cookie reference for use in the other data functions.
Note:
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
Function: vstr_data_del()
Returns: Nothing
Type: void
Parameter[1]: Vstr string
Type[1]: struct Vstr_conf *
Parameter[2]: Cookie reference for configuration data
function
Type[2]: unsigned int
Explanation:
This function will release the reference on the configuration data, and allow
the cookie to be reused on a later vstr_data_add() call.
Note:
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
Function: vstr_data_get()
Returns: Data for configuration data function
Type: void *
Parameter[1]: Vstr string
Type[1]: struct Vstr_conf *
Parameter[2]: Cookie reference for configuration data
function
Type[2]: unsigned int
Explanation:
This function will get the data for the configuration data storage
function.
Note:
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
Function: vstr_data_set()
Returns: Nothing
Type: void
Parameter[1]: Vstr string
Type[1]: struct Vstr_conf *
Parameter[2]: Cookie reference for configuration data
function
Type[2]: unsigned int
Parameter[3]: Reference to data to store in the
configuration
Type[3]: struct Vstr_ref *
Explanation:
This function will set the data for the configuration data storage
function.
Note:
If the configuration (Parameter[1]) is NULL, then the global configuration is
used.
Storing a reference that is NULL is valid, and will act like storing a
reference to NULL.
All allocations are done at vstr_data_add() time, so this function can never
fail.
Function: vstr_swap_conf()
Returns: TRUE on success and FALSE on failure
Type: int
Parameter[1]: Vstr string
Type[1]: struct Vstr_base *
Parameter[2]: New Vstr configuration; returned old Vstr
configuration
Type[2]: struct Vstr_conf **
Explanation:
This function will swap a Vstr configuration into a Vstr string possibly
changing the Vstr configuration to be compatible with the Vstr string. On
success the Vstr configuration that was being used by the Vstr string is
returned.
Note:
Using this function allows you to use vstr_add_fmt() and vstr_add_vfmt() on a
Vstr that you don't own, by doing...
if (vstr_swap_conf(notmy_vstr_string, &my_vstr_conf))
{
vstr_add_fmt(notmy_vstr_string, ... );
vstr_swap_conf(notmy_vstr_string, &my_vstr_conf);
}
...note that the last call swaps the configuration back. However if you are
not using any custom specifiers then you can just call vstr_add_sysfmt()
instead.
The function will return 0 if it needs to allocate memory and cannot do
so.
