Experimental Physics and
Industrial Control System

The name epicsThreadMustJoin() would tell someone who knows our other API names that the routine will call cantProceed() if it fails.

I would expect a routine called epicsThreadTryJoin() to be functionally equivalent to the glibc extension pthread_tryjoin_np() that Michael found. It should also be equivalent to passing in a timeout of zero to a timed version.

Might pthreads allow us to write our own equivalent to pthread_timedjoin_np() using waitpid()? I'm hoping for something that might also work on RTEMS-5, MacOS and non-glibc Linux targets...
