.SH ARGUMENTS

.IP "gnutls_psk_server_credentials_t         cred" 12

.IP "gnutls_psk_server_credentials_function         * func" 12

is the callback function

.SH "DESCRIPTION"

This function can be used to set a callback to retrieve the user's PSK credentials.

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.
