NAME         top

       gnutls_psk_set_server_credentials_function2 - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       cred, gnutls_psk_server_credentials_function2 func);

ARGUMENTS         top

       gnutls_psk_server_credentials_t cred
                   is a gnutls_psk_server_credentials_t type.

       gnutls_psk_server_credentials_function2 func
                   is the callback function

DESCRIPTION         top

       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 gnutls_datum_t* username,
       gnutls_datum_t* key);

       This callback function has the same semantics as that of
       gnutls_psk_set_server_credentials_function(), but it allows
       non-string usernames to be used.

        username contains the actual username.  The  key must be filled
       in using the gnutls_malloc().

       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.
