gnutls_sign_callback_set(3) API function


#include <gnutls/gnutls.h>

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


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.


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().
