NAME
       gnutls_psk_set_server_credentials_function2 - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       void
       gnutls_psk_set_server_credentials_function2(gnutls_psk_server_credentials_t
       cred, gnutls_psk_server_credentials_function2 func);

ARGUMENTS
       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
       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.
