Result:

Main(): Waited and joined with 3 threads. Final value of count = 0. Done.
Starting watch_count(): thread 1
inc_count(): thread 2, count = 1, unlocking mutex
inc_count(): thread 3, count = 2, unlocking mutex
watch_count(): thread 1 Count= 2. Going into wait...
inc_count(): thread 2, count = 3, unlocking mutex
inc_count(): thread 3, count = 4, unlocking mutex
inc_count(): thread 2, count = 5, unlocking mutex
inc_count(): thread 3, count = 6, unlocking mutex
inc_count(): thread 2, count = 7, unlocking mutex

inc_count(): thread 2, count = 9, unlocking mutex
inc_count(): thread 3, count = 10, unlocking mutex
inc_count(): thread 2, count = 11, unlocking mutex
inc_count(): thread 3, count = 12  Threshold reached. Just sent signal.
inc_count(): thread 3, count = 12, unlocking mutex
watch_count(): thread 1 Condition signal received. Count= 12
watch_count(): thread 1 Updating the value of count...
watch_count(): thread 1 count now = 137.
watch_count(): thread 1 Unlocking mutex.
inc_count(): thread 2, count = 138, unlocking mutex
inc_count(): thread 3, count = 139, unlocking mutex
inc_count(): thread 2, count = 140, unlocking mutex
inc_count(): thread 3, count = 141, unlocking mutex
inc_count(): thread 2, count = 142, unlocking mutex
inc_count(): thread 3, count = 143, unlocking mutex
inc_count(): thread 2, count = 144, unlocking mutex
inc_count(): thread 3, count = 145, unlocking mutex

All three examples are ported from the following pthread tutorial: https://computing.llnl.gov/tutorials/pthreads/

I'm new to rtos, so if you find any silly mistakes, just let me know. Thanks!
