I am moving a rendering engine of sorts from Carbon to Cocoa. It is

event handler (on the main thread) to handle things that are not

safe.
In Carbon, I would Post an event and call:
err = MPWaitOnQueue (pTaskInfo->mSignalQueueID, (void **)
&pTaskInfo->mQueueMessage, NULL, NULL, kDurationForever);
if (pTaskInfo->mQueueMessage == kMyTaskSignalAbort)
pTaskInfo->mAbort = true;
When the main thread would be done with the task, it would call:
MPNotifyQueue (pTaskInfo->mSignalQueueID, (void *)
kMyTaskSignalContinue,
NULL, NULL);
Is there a good online reference to the Cocoa equivalent of this?
Any pointers as to how I should structure this in Cocoa?
You could probably use:
-[NSObject performSelectorOnMainThread:withObject:waitUntilDone:];
How much of Cocoa is thread safe?
Very little, and the documentation on that topic is somewhat lacking.
