ARCHIVE_WRITE_DATA(3)	 BSD Library Functions Manual	 ARCHIVE_WRITE_DATA(3)

NAME
     archive_write_data — 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);

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.
