gnutls_handshake_set_hook_function - API function
#include <gnutls/gnutls.h>
void gnutls_handshake_set_hook_function(gnutls_session_t session,
unsigned int htype, int post, gnutls_handshake_hook_func func);
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 post GNUTLS_HOOK_* depending on when the hook function should
be called
gnutls_handshake_hook_func func
is the function to be called
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 sent/generated
use GNUTLS_HOOK_PRE as post 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.
Note to hook at all handshake messages use an htype of
GNUTLS_HANDSHAKE_ANY.
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.
