archive_write_set_bytes_per_block
ARCHIVE_WRITE_BLOCKSIZE(3) BSD Library Functions Manual ARCHIVE_WRITE_BLOCKSIZE(3)
NAME
archive_write_get_bytes_per_block, archive_write_set_bytes_per_block, archive_write_get_bytes_in_last_block,
archive_write_set_bytes_in_last_block -- functions for creating archives
LIBRARY
Streaming Archive Library (libarchive, -larchive)
SYNOPSIS
#include <archive.h>
int
archive_write_get_bytes_per_block(struct archive *);
int
archive_write_set_bytes_per_block(struct archive *, int bytes_per_block);
int
archive_write_get_bytes_in_last_block(struct archive *);
int
archive_write_set_bytes_in_last_block(struct archive *, int);
DESCRIPTION
archive_write_set_bytes_per_block()
Sets the block size used for writing the archive data. Every call to the write callback function, except possibly the last one, will
use this value for the length. The default is to use a block size of 10240 bytes. Note that a block size of zero will suppress
internal blocking and cause writes to be sent directly to the write callback as they occur.
archive_write_get_bytes_per_block()
Retrieve the block size to be used for writing. A value of -1 here indicates that the library should use default values. A value of
zero indicates that internal blocking is suppressed.
archive_write_set_bytes_in_last_block()
Sets the block size used for writing the last block. If this value is zero, the last block will be padded to the same size as the
other blocks. Otherwise, the final block will be padded to a multiple of this size. In particular, setting it to 1 will cause the
final block to not be padded. For compressed output, any padding generated by this option is applied only after the compression.
The uncompressed data is always unpadded. The default is to pad the last block to the full block size (note that
archive_write_open_filename() will set this based on the file type). Unlike the other ``set'' functions, this function can be called
after the archive is opened.
archive_write_get_bytes_in_last_block()
Retrieve the currently-set value for last block size. A value of -1 here indicates that the library should use default values.
RETURN VALUES
archive_write_set_bytes_per_block() and archive_write_set_bytes_in_last_block() return ARCHIVE_OK on success, or ARCHIVE_FATAL.
archive_write_get_bytes_per_block() and archive_write_get_bytes_in_last_block() return currently configured block size (-1 indicates the
default block size), or ARCHIVE_FATAL.
ERRORS
Detailed error codes and textual descriptions are available from the archive_errno() and archive_error_string() functions.
