ZIP_FDOPEN(3) Introduction to Library Functions ZIP_FDOPEN(3)
zip_fdopen - open zip archive using open file descriptor
libzip (-lzip)
#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 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.
libzip(3), zip_close(3), zip_error_strerror(3), zip_open(3)
zip_fdopen() was added in libzip 1.0.

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.
