zip_fdopen
— open
zip archive using open file descriptor
#include
<zip.h>
zip_t *
zip_fdopen
(int
fd, int flags,
int *errorp);
The zip archive specified by the open file descriptor
fd is opened and a pointer to a struct
zip, used to manipulate the archive, is returned. In contrast to
zip_open(3),
using zip_fdopen
the archive can only be opened in
read-only mode. The fd argument may not be used any
longer after calling zip_fdopen
. The
flags are specified by
or'ing
the following values, or 0 for none of them.
ZIP_CHECKCONS
- Perform additional stricter consistency checks on the archive, and error
if they fail.
If an error occurs and errorp is
non-NULL
, it will be set to
the corresponding error code.
Upon successful completion zip_fdopen
()
returns a struct zip pointer, and
fd should not be used any longer, nor passed to
close(2).
Otherwise, NULL
is returned and
*errorp is set to indicate the error. In the error
case, fd remains unchanged.
The file specified by fd is prepared for use
by
libzip(3)
unless:
- [
ZIP_ER_INCONS
]
- Inconsistencies were found in the file specified by
path. This error is often caused by specifying
ZIP_CHECKCONS
but can also happen without it.
- [
ZIP_ER_INVAL
]
- The flags argument is invalid. Not all
zip_open(3)
flags are allowed for
zip_fdopen
, see
