The asynchronous handler is installed using:
OTNotifyUPP theHandler = NewOTNotifyUPP( EventHandler );
err = OTAsyncOpenEndpointInContext( OTCreateConfiguration(kTCPName), 0,
&info, theHandler, 0, NULL );
The above code doesn't make sense to me. The notifier casts the
context parameter to an (EPInfo *), but when you call
OTAsyncOpenEndpointInContext you pass 0 to the contextPtr parameter
(the 5th parameter) of OTAsyncOpenEndpointInContext. Surely you
should allocate an EPInfo instructure just before you open and pass
its address in to the contextPtr parameter, right?
On MacOS 9.x cookie in EventHandler contains the endpoint. On OS X it is a
null pointer.
Well, that's interesting. I just checked the source for the OT
compatibility library in Mac OS X 10.1 and it definitely tries to
pass the EndpointRef to the cookie parameter. Are you sure you're
not mixing up your cookies and your contexts?
