SYNOPSIS         top

       #include <gnutls/gnutls.h>

       void
       gnutls_psk_set_client_credentials_function(gnutls_psk_client_credentials_t
       cred, gnutls_psk_client_credentials_function         * func);

ARGUMENTS         top

       gnutls_psk_client_credentials_t         cred
                   is a gnutls_psk_server_credentials_t type.

       gnutls_psk_client_credentials_function         * func
                   is the callback function

DESCRIPTION         top

       This function can be used to set a callback to retrieve the username
       and password for client PSK authentication.  The callback's function
       form is: int (*callback)(gnutls_session_t, char** username,
       gnutls_datum_t* key);

       The  username and  key ->data must be allocated using
       gnutls_malloc().
        username should be ASCII strings or UTF-8 strings prepared using the
       "SASLprep" profile of "stringprep".

       The callback function will be called once per handshake.

       The callback function should return 0 on success.  -1 indicates an
       error.
