NSFileHandle thread safe ?
NSFileHandle thread safe ?

I am using an NSFileHandle to read/write to a device. For reading I am using
the :readInBackgroundAndNotifyForModes: method. The device is asynchronous
and can return data to the Mac at any time.
Now, when device data is read in the NSFileHandle background thread,
NSFileHandle posts an NSFileHandleReadCompletionNotification notification.
My question is, are these notifications executed in the context of the
NSFileHandle background thread or are they executed off of the main run loop
? This has a bearing on whether I can :writeData: from both the main thread
AND the NSFileHandleReadCompletionNotification method. The documentation
only specifies that the notification is posted, but not it's context.
Opinions ?
Thanx -
Alec Carlson
