The NSValue class is capable of wrapping a pointer inside an object.
You can sometimes get away with simply casting a pointer or integer to
id, though it may not be a good idea, but
detachNewThreadSelector:toTarget:withObject: needs real objects
because it retains them when the thread is detached and releases them
when it terminates, and only real objects respond to retain and
release messages.
mmmhhhh.....
I've tried doing this:
NSValue *value;
value = [NSValue valueWithPointer:@encode(PortAudioStream *)];
[value retain];
[NSThread detachNewThreadSelector: @selector(playForSure:)
toTarget: nil withObject:value];
...
The called selector is:
- (void)playForSure:(PortAudioStream *)stream;
{ NSLog(@"selector called");}
but the selector is not called in any way.
I've tried retainig "value" but nothing...
Do you have any clues?
Thank you again.
