Аргументы (Arguments)

gnutls_session_t session
                   is a gnutls_session_t type

       unsigned int htype
                   the gnutls_handshake_description_t of the message to
                   hook at

       int when    GNUTLS_HOOK_* depending on when the hook function
                   should be called

       gnutls_handshake_hook_func func
                   is the function to be called

Описание (Description)

This function will set a callback to be called after or before
       the specified handshake message has been received or generated.
       This is a generalization of
       gnutls_handshake_set_post_client_hello_function().

       To call the hook function prior to the message being generated or
       processed use GNUTLS_HOOK_PRE as  when parameter,
       GNUTLS_HOOK_POST to call after, and GNUTLS_HOOK_BOTH for both
       cases.

       This callback must return 0 on success or a gnutls error code to
       terminate the handshake.

       To hook at all handshake messages use an  htype of
       GNUTLS_HANDSHAKE_ANY.

Предупреждение (Warning)

You should not use this function to terminate the handshake based
       on client input unless you know what you are doing. Before the
       handshake is finished there is no way to know if there is a
       man-in-the-middle attack being performed.
