ARCHIVE_WRITE_DATA(3archive) NAME archive_write_data, archive_write_data_block - functions for creating archives LIBRARY Streaming Archive Library (libarchive, -larchive) SYNOPSIS #include <archive.h> la_ssize_t archive_write_data(struct archive *, const void *, size_t); la_ssize_t archive_write_data_block(struct archive *, const void *, size_t size, int64_t offset); DESCRIPTION archive_write_data() Write data corresponding to the header just written. archive_write_data_block() Write data corresponding to the header just written. This is like archive_write_data() except that it performs a seek on the file being written to the specified offset before writing the data. This is useful when restoring sparse files from archive formats that support sparse files. Returns number of bytes written or -1 on error. (Note: This is currently not supported for Tn archive_write han- dles, only for Tn archive_write_disk handles. RETURN VALUES This function returns the number of bytes actually written, or a nega- tive error code on error. ERRORS Detailed error codes and textual descriptions are available from the archive_errno() and archive_error_string() functions. BUGS In libarchive 3.x, this function sometimes returns zero on success instead of returning the number of bytes written. Specifically, this occurs when writing to an Vt archive_write_disk handle. Clients should treat any value less than zero as an error and consider any non-nega- tive value as success.
