NAME
       gnutls_psk_set_server_credentials_function2 - API function

SYNOPSIS
       #include	<gnutls/gnutls.h>

       void gnutls_psk_set_server_credentials_function2(gnutls_psk_server_cre-
       dentials_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  (*call-
       back)(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 us-
       ing 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 er-
       ror.
