int gnutls_server_name_get(gnutls_session_t session, void * data, size_t * data_length, unsigned int * type, unsigned int indx);
is a gnutls_session_t structure.
void * data
will hold the data
size_t * data_length
will hold the data length. Must hold the maximum size of data.
unsigned int * type
will hold the server name indicator type
unsigned int indx
