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 <bug-gnutls@gnu.org>. .SH COPYRIGHT Copyright \(co 2008 Free Software Foundation. .br Permission is granted to make and distribute verbatim copies of this manual provided the copyright notice and this permission notice are preserved on all copies. .SH "SEE ALSO" The full documentation for .B gnutls is maintained as a Texinfo manual.
