archive_write_fail, archive_write_close, archive_write_finish, archive_write_free — functions for creating archives
Streaming Archive Library (libarchive, -larchive)
archive_write_fail(struct archive *);
archive_write_close(struct archive *);
archive_write_finish(struct archive *);
archive_write_free(struct archive *);
Always returns ARCHIVE_FATAL. This marks the archive object as being unusable; after calling this function, the only call that can succeed is archive_write_free() to release the resources. This can be used to speed recovery when the archive creation must be aborted. Note that the created archive is likely to be malformed in this case;
Complete the archive and invoke the close callback.
This is a deprecated synonym for archive_write_free().
Invokes archive_write_close() if necessary, then releases all resources. If you need detailed information about archive_write_close() failures, you should be careful to call it separately, as you cannot obtain error information after archive_write_free() returns.
These functions return ARCHIVE_OK on success, or ARCHIVE_FATAL.
Detailed error codes and textual descriptions are available from the archive_errno() and archive_error_string() functions.
