openpam_readline
—
read a line from a file
This function is deprecated and may be removed in a future
release without further warning. The
openpam_readlinev
()
function may be used to achieve similar results.
The
openpam_readline
()
function reads a line from a file, and returns it in a NUL-terminated buffer
allocated with
malloc(3).
The
openpam_readline
()
function performs a certain amount of processing on the data it reads:
- Comments (introduced by a hash sign) are stripped.
- Blank lines are ignored.
- If a line ends in a backslash, the backslash is stripped and the next line
is appended.
If lineno is not
NULL
, the integer variable it points to is
incremented every time a newline character is read.
If lenp is not NULL
,
the length of the line (not including the terminating NUL character) is
stored in the variable it points to.
The caller is responsible for releasing the returned buffer by
passing it to
free(3).
The openpam_readline
() function returns
NULL
on failure.
The openpam_readline
() function is an
OpenPAM extension.
The openpam_readline
() function and this
manual page were developed for the FreeBSD Project
by ThinkSec AS and Network Associates Laboratories, the Security Research
Division of Network Associates, Inc. under DARPA/SPAWAR contract
N66001-01-C-8035 (“CBOSS”), as part of the DARPA CHATS
research program.
