Hi,
I'd like to know the low-level equivalent of the functions implemented
by
NSLock. I'm looking for the exact same set of functions but without the
Cocoa overhead (like NSDate to specify a max waiting time).
I think it's a wrapper for pthread_mutex_* (and NSConditionalLock is a
wrapper for pthread_cond_*).
Have you done any measurements of NSLock performance (especially in the
context of your app) to determine that it's a performance problem? It
doesn't seem to do all that much more than call pthread.
