ARCHIVE_WRITE_DATA(3) manual page 
== NAME == 
'''archive_write_data''' 
- functions for creating archives 
== LIBRARY == 
Streaming Archive Library (libarchive, -larchive) 
== SYNOPSIS == 
'''<nowiki>#include <archive.h></nowiki>''' 
<br> 
''la_ssize_t'' 
<br> 
'''archive_write_data'''(''struct archive *'', ''const void *'', ''size_t''); 
== DESCRIPTION == 
Write data corresponding to the header just written. 
== 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.
