gnutls_sign_callback_set — API function
#include <gnutls/gnutls.h>
void
            gnutls_sign_callback_set( | 
            gnutls_session_t | session, | 
| gnutls_sign_func | sign_func, | |
| void * | userdata); | 
          
is a gnutls session
function pointer to application's sign callback.
void pointer that will be passed to sign callback.
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().
The full documentation for gnutls is maintained as a Texinfo manual. If the info and gnutls programs are properly installed at your site, the command
info gnutls
should give you access to the complete manual.
