gnutls_handshake_set_post_client_hello_function - API function SYNOPSIS
#include <gnutls/gnutls.h> void gnutls_handshake_set_post_client_hello_function(gnutls_session_t session, gnutls_handshake_post_client_hello_func func); ARGUMENTS
gnutls_session_t session is a gnutls_session_t structure. gnutls_handshake_post_client_hello_func func is the function to be called DESCRIPTION
This function will set a callback to be called after the client hello has been received (callback valid in server side only). This allows the server to adjust settings based on received extensions. Those settings could be ciphersuites, requesting certificate, or anything else except for version negotiation (this is done before the hello message is parsed). This callback must return 0 on success or a gnutls error code to terminate the handshake. 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. REPORTING BUGS

gnutls_sign_algorithm_get_requested - API function SYNOPSIS
#include <gnutls/gnutls.h> int gnutls_sign_algorithm_get_requested(gnutls_session_t session, size_t indx, gnutls_sign_algorithm_t * algo); ARGUMENTS
gnutls_session_t session is a gnutls_session_t structure. size_t indx is an index of the signature algorithm to return gnutls_sign_algorithm_t * algo the returned certificate type will be stored there DESCRIPTION
Returns the signature algorithm specified by index that was requested by the peer. If the specified index has no data available this func- tion returns GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE. If the negotiated TLS version does not support signature algorithms then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned even for the first index. The first index is 0. This function is useful in the certificate callback functions to assist in selecting the correct certificate. RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned. SINCE
