ZIP_FDOPEN(3) Library Functions Manual ZIP_FDOPEN(3)NAMEzip_fdopen - open zip archive using open file descriptor
LIBRARY
libzip (-lzip)
SYNOPSIS
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 fol‐
lowing 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 corre‐
sponding 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.
