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), usingzip_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 completionzip_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_CHECKCONSbut 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.
