zip_fdopen - open zip archive using open file descriptor


libzip (-lzip)


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