—
open zip archive
LIBRARY¶
libzip (-lzip)SYNOPSIS¶
#include <zip.h>
zip_t *
zip_open(const
char *path, int
flags, int
*errorp);
zip_t *
zip_open_from_source(zip_source_t
*zs, int flags,
zip_error_t *ze);
DESCRIPTION¶
Thezip_open() function opens the zip archive specified
by path and returns a pointer to a
struct zip, used to manipulate the archive. 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.
ZIP_CREATE- Create the archive if it does not exist.
ZIP_EXCL- Error if archive already exists.
ZIP_TRUNCATE- If archive exists, ignore its current contents. In other words, handle it the same way as an empty archive.
ZIP_RDONLY- Open archive in read-only mode.
If an error occurs and errorp is
non-NULL, it will be set to the corresponding error
code.
The zip_open_from_source() function opens
a zip archive encapsulated by the zip_source zs using
the provided flags. In case of error, the zip_error
ze is filled in.
RETURN VALUES¶
Upon successful completionzip_open() and
zip_open_from_source() return a struct
zip pointer. Otherwise, NULL is returned and
zip_open() sets *errorp to
indicate the error, while
zip_open_from(source) sets
ze to indicate the error.
