[Insight-developers] Re: itkSemaphore on Mac

[Joshua Cates]

Hi Brad,

This is not good news.  From discussions I've seen on the web, Mac OS 
X is supposed to support pthread semaphores, but there may be another 
way.  I've seen reference to IPC semaphores on the mac.  I'll do some 
searching.

Josh.
