Subject Re: No timed lock on MacOS
Date Wed, 05 Apr 2017 12:16:21 GMT
Hmmm.... Looking over the timed stuff, it seems that semtimedop()
is used incorrectly.

For both pthread_mutex_timedlock() and sem_timedwait(), the
timeout variable is the actual wallclock time that the wait
expires (eg: now+5mins). But, from what I can read about semtimedop(), its
timeout really is a timeout (5mins). But it seems that we use it
as if it was wall-clock time, which is WAY wrong...

Can someone check to see what exactly the timeout value is for
semtimedop()? Is it a delta or a wall-clock?
