libzip (-lzip)

SYNOPSIS


.In 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_READ]
  A read error occurred; see errno for details.
[ZIP_ER_SEEK]
  The file specified by fd does not allow seeks.
