ARCHIVE_WRITE_DATA(3)</p>
<p style="margin-top: 1em"><b>NAME</b></p>
<p style="margin-left:6%;"><b>archive_write_data</b>
— functions for creating archives</p>
<p style="margin-top: 1em"><b>LIBRARY</b></p>
<p style="margin-left:6%;">Streaming Archive Library
(libarchive, -larchive)</p>
<p style="margin-top: 1em"><b>SYNOPSIS</b></p>
<p style="margin-left:6%;"><b>#include
<archive.h></b></p>
<p style="margin-left:6%; margin-top: 1em"><i>la_ssize_t</i></p>
<p style="margin-left:12%;"><b>archive_write_data</b>(<i>struct archive *</i>,
<i>const void *</i>, <i>size_t</i>);</p>
<p style="margin-top: 1em"><b>DESCRIPTION</b></p>
<p style="margin-left:6%;">Write data corresponding to the
header just written.</p>
<p style="margin-top: 1em"><b>RETURN VALUES</b></p>
<p style="margin-left:6%;">This function returns the number
of bytes actually written, or a negative error code on
error.</p>
<p style="margin-top: 1em"><b>ERRORS</b></p>
<p style="margin-left:6%;">Detailed error codes and textual
descriptions are available from the <b>archive_errno</b>()
and <b>archive_error_string</b>() functions.</p>
<p style="margin-top: 1em"><b>BUGS</b></p>
<p style="margin-left:6%;">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 <i>archive_write_disk</i> handle. Clients
should treat any value less than zero as an error and
consider any non-negative value as success.</p>
