Duane -
What is the recipe for this seemingly simple task (that IOSyncer handles very nicely) with IOCommandGate.
Easy recipe:
Sync Call is made done = false; Send I/O asynchronously IOCommandGate::runAction() while (!done) IOCommandGate::commandSleep(&done,TH_UNINT);
On workloop completion thread: done = true; IOCommandGate::commandWakeup(&done);
This is the part that I'm usually confused on. Does the thread have to have the gate to call commandWakeup or can commandWakeup be called anytime? The completion thread is the callback for the completion of IO (IOStorageCompletion). Can that callback just call commandWakeup or do I have to enter the gate first using runAction and call commandWakeup from the runAction call back? Thanks again. This was very helpful. ...Duane _______________________________________________ Do not post admin requests to the list. They will be ignored.
