ZIP_FDOPEN(3) Library Functions Manual 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.
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:
[]
Inconsistencies were found in the file specified by path. This error is often caused by specifying ZIP_CHECKCONS but can also happen without it.
[]
The flags argument is invalid. Not all zip_open(3) flags are allowed for zip_fdopen, see DESCRIPTION.
[]
Required memory could not be allocated.
[]
The file specified by fd is not a zip archive.
[]
The file specified by fd could not be prepared for use by libzip(3).
[]
A read error occurred; see errno for details.
[]
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.
