gpgme idle, Re: gpgme progress meter callback

[Jacob Perkins]

Yes, I saw the compiler warning, but I'm new to c and did not know how
to pass a function pointer.

Anyway, how does gpgme tell if it is idle?  I set an idle function with
register_idle, but it never seems to be called.  Is this feature not
completely supported yet, or do I need to do more with the I/O callback
interface?

gpgme_register_idle (idle);
...
void idle(){
	g_print ("idleing\n");
}
