NAME
       gnutls_psk_set_server_credentials_function - API function

SYNOPSIS
       #include <gnutls/gnutls.h>

       void	 gnutls_psk_set_server_credentials_function(gnutls_psk_server_credentials_t						     cred,
       gnutls_psk_server_credentials_function						  * func);

ARGUMENTS
       gnutls_psk_server_credentials_t						   cred
		   is a gnutls_psk_server_credentials_t structure.

       gnutls_psk_server_credentials_function						  * 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 char* username, gnutls_datum_t* key);

	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.
