nsthread - what is detatch & non-detatch threads in iPhone -

whats difference between detach , non-detach thread in iphone? iphone "threading programming guide" documentation says

• by default nsthread class creates detach threads
• and says detached thread means thread's resources automatically reclaimed system when thread exits. in same way , how happen in non-detach threads?

thank you. suse

this relates underlying pthread implementation. read on pthread_detach , pthread_join understand differences.

in practice, don't care , cocoa/nsthread right thing automatically.

and clarify, there's no way create non-detached thread using nsthread. you'd have use low-level thread api that.
