Finds cnd_wait, cnd_timedwait, wait, wait_for, orwait_until function calls when the function is not invoked from a loop that checks whether a condition predicate holds or the function has a condition parameter.

if (condition_predicate) { condition.wait(lk); }

if (condition_predicate) { if (thrd_success != cnd_wait(&condition, &lock)) { } }

This check corresponds to the CERT C++ Coding Standard ruleCON54-CPP. Wrap functions that can spuriously wake up in a loop. and CERT C Coding Standard ruleCON36-C. Wrap functions that can spuriously wake up in a loop.
