When output is text, a null terminated string is written to \fIoutput\fP and its string length is written to \fIoutput_size\fP (without null terminator). If the buffer is too small, \fIoutput_size\fP will contain the expected buffer size (with null terminator for text) and return \fBGNUTLS_E_SHORT_MEMORY_BUFFER\fP. In versions previously to 3.6.0 this function included the null terminator to \fIoutput_size\fP . After 3.6.0 the output size doesn't include the terminator character. .SH "RETURNS" \fBGNUTLS_E_SUCCESS\fP (0) on success or a negative error code on error. .SH "SINCE" 2.12.0 .SH "REPORTING BUGS" Report bugs to . .br Home page: https://www.gnutls.org .SH COPYRIGHT Copyright \(co 2001-2023 Free Software Foundation, Inc., and others. .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.
