NAME
       gnutls_sign_callback_set - API function

SYNOPSIS
       #include <gnutls/compat.h>

       void	    gnutls_sign_callback_set(gnutls_session_t	      session,
       gnutls_sign_func sign_func, void * userdata);

ARGUMENTS
       gnutls_session_t session
		   is a gnutls session

       gnutls_sign_func sign_func
		   function pointer to application's sign callback.

       void * userdata
		   void pointer that will be passed to sign callback.

DESCRIPTION
       Set the callback function.  The function must have this prototype:

       typedef int (*gnutls_sign_func) (gnutls_session_t session, void	*user-
       data, gnutls_certificate_type_t cert_type, const gnutls_datum_t * cert,
       const gnutls_datum_t * hash, gnutls_datum_t * signature);

       The  userdata parameter is passed to the  sign_func verbatim,  and  can
       be used to store application-specific data needed in the callback func-
       tion.  See also gnutls_sign_callback_get().

DEPRECATED
       Use   the   PKCS    11	 or    gnutls_privkey_t    interfacess	  like
       gnutls_privkey_import_ext() instead.
