The callback's function form is: int (*callback)(gnutls_session_t, const char* username, gnutls_datum_t* key); \fIusername\fP contains the actual username. The \fIkey\fP must be filled in using the \fBgnutls_malloc()\fP. In case the callback returned a negative number then gnutls will assume that the username does not exist. The callback function will only be called once per handshake. The callback function should return 0 on success, while \-1 indicates an error. .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.
