ARCHIVE_WRITE_DATA(3) BSD Library Functions Manual ARCHIVE_WRITE_DATA(3)
|
||
|
|
|
||
|
|
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 writ-
|
||
|
|
ten or -1 on error. (Note: This is currently not supported for
|
||
|
|
archive_write handles, only for archive_write_disk handles.
|
||
|
|
|
||
|
|
RETURN VALUES
|
||
|
|
This function returns the number of bytes actually written, or a negative
|
||
|
|
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 archive_write_disk handle. Clients should
|
||
|
|
treat any value less than zero as an error and consider any non-negative
|
||
|
|
value as success.
