I think I may have stumbled onto my problem. I am relatively new to
pthreads, so it may be a newbie thing.
My code sends data to a USB device using pthreads to do the transfers
and poll for status. Each time a data write or a control read/write
transaction is executed a new pthread is created which then sends the
data with a blocking call, sets some status flags and exits into
oblivion.
However it appears that after roughly 4000 or so of these threads are
created, execute and die, things start going wacko.
Am I running out of threads?
And If so, do I need to keep the data write thread and control
read/write thread alive for the duration of my program, letting them
sleep until the next operation is required, waking them to do the work,
and sleeping them again until done.
Or I guess I could also do the CFRunLoop thing too.
