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 *userdata, 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
       function.  See also gnutls_sign_callback_get().

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