zip_fdopen
NAME
zip_fdopen
— open
zip archive using open file descriptor
LIBRARY
libzip (-lzip)
SYNOPSIS
#include
<zip.h>
zip_t *
zip_fdopen
(int
fd, int flags,
int *errorp);
DESCRIPTION
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.
RETURN VALUES
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.
ERRORS
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 DESCRIPTION. - [
ZIP_ER_MEMORY
] - Required memory could not be allocated.
- [
ZIP_ER_NOZIP
] - The file specified by fd is not a zip archive.
- [
ZIP_ER_OPEN
] - The file specified by fd could not be prepared for use by libzip(3).
- [
ZIP_ER_OPNOTSUPP
] - This functionality has been disabled at compile time.
- [
ZIP_ER_READ
] - A read error occurred; see errno for details.
- [
ZIP_ER_SEEK
] - The file specified by fd does not allow seeks.
