Should have space for 8 bytes. .SH "DESCRIPTION" This function is the same as \fBgnutls_record_recv()\fP, except that it returns in addition to data, the sequence number of the data. This is useful in DTLS where record packets might be received out\-of\-order. The returned 8\-byte sequence number is an integer in big\-endian format and should be treated as a unique message identification. .SH "RETURNS" The number of bytes received and zero on EOF. A negative error code is returned in case of an error. The number of bytes received might be less than \fIdata_size\fP . .SH "SINCE" 3.0 .SH "REPORTING BUGS" Report bugs to <bugs@gnutls.org>. .br Home page: http://www.gnutls.org .SH COPYRIGHT Copyright \(co 2001-2014 Free Software Foundation, Inc. .br Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. .SH "SEE ALSO" The full documentation for .B gnutls is maintained as a Texinfo manual.
