NAME
     pptthhrreeaaddccoonnddttiimmeeddwwaaiitt - wait on a condition variable for a specific
     amount of time

SYNOPSIS
     ##iinncclluuddee <>

     int
     pptthhrreeaaddccoonnddttiimmeeddwwaaiitt(pthreadcondt *cond, pthreadmutext *mutex,
         const struct timespec *abstime);

DESCRIPTION
     The pptthhrreeaaddccoonnddttiimmeeddwwaaiitt() function atomically blocks the current
     thread waiting on the condition variable specified by cond, and unblocks
     the mutex specified by mutex.  The waiting thread unblocks only after
     another thread calls pthreadcondsignal(3), or pthreadcondbroadcast(3)
     with the same condition variable, or if the system time reaches the time
     specified in abstime, and the current thread reacquires the lock on
     mutex.

RETURN VALUES
     If successful, the pptthhrreeaaddccoonnddttiimmeeddwwaaiitt() function will return zero.
     Otherwise an error number will be returned to indicate the error.

EERRRROORRSS
     pptthhrreeaaddccoonnddttiimmeeddwwaaiitt() will fail if:

     [EINVAL]           The value specified by cond, mutex or abstime is
                        invalid.

     [ETIMEDOUT]        The system time has reached or exceeded the time spec-
                        ified in abstime.
