SSL_CTX_set_client_cert_cb() sets the client_cert_cb() callback, that is
called when a client certificate is requested by a server and no certificate
was yet set for the SSL object.
When B<client_cert_cb()> is NULL, no callback function is used.
When client_cert_cb() is NULL, no callback function is used.
SSL_CTX_get_client_cert_cb() returns a pointer to the currently set callback
