BPX1CSE (cond_setup) example

The following code sets up the invoker to suspend processing until any of the specified events (CW_INTRPT or CW_CONDVAR) occurs. The BPX1CTW (cond_timed_wait) or BPX1CWA (cond_wait) service is used to actually suspend processing. For the callable service, see cond_setup (BPX1CSE, BPX4CSE) — Set up to receive event notifications. AMODE 64 callers use BPX4CSE (cond_setup) example.
