NAME

6       gnutls_sign_callback_set - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       void         gnutls_sign_callback_set(gnutls_session_t         session,
12       gnutls_sign_func sign_func, void * userdata);
13

ARGUMENTS

15       gnutls_session_t session
16                   is a gnutls session
17
18       gnutls_sign_func sign_func
19                   function pointer to application's sign callback.
20
21       void * userdata
22                   void pointer that will be passed to sign callback.
23

DESCRIPTION

25       Set the callback function.  The function must have this prototype:
26
27       typedef int (*gnutls_sign_func) (gnutls_session_t session, void  *user‐
28       data, gnutls_certificate_type_t cert_type, const gnutls_datum_t * cert,
29       const gnutls_datum_t * hash, gnutls_datum_t * signature);
30
31       The userdata parameter is passed to the sign_func verbatim, and can  be
32       used  to  store  application-specific data needed in the callback func‐
33       tion.  See also gnutls_sign_callback_get().
