Hello All,

I am newbie in mac. i have query about following things with semaphore

i am trying to use mach semaphore in IOKit. i have following questions :-

1: Do mach semaphore provide functions to get semaphore count? if not the why?

2: For mach semaphore one function available which is semaphore_signal_thread(), but for mac os x 10.6.2 i didn't found in semaphore.h?

3: I have try to go with POSIX semaphore, but it is not possible to implement in kernel.

Thanks,

Sheetal.
