Normal applications should use .Xr pthread_cond_timedwait 3 together with .Xr pthread_cond_broadcast 3 for typical safe suspension with cooperation of the thread being suspended, or .Xr pthread_suspend_np 3 and .Xr pthread_resume_np 3 in some specific situations, instead. .Ef .Pp Passing the thread identifier of the calling thread .Po see .Xr thr_self 2 .Pc to .Fn thr_wake sets a thread's flag to cause the next signal-interruptible sleep of that thread in the kernel to fail immediately with the .Er EINTR error. The flag is cleared by an interruptible sleep attempt or by a call to -.Xr thr_suspend 2. +.Xr thr_suspend 2 . This is used by the system threading library to implement cancellation. .Pp If .Fa id is not equal to the current thread identifier, the specified thread is woken up if suspended by the .Xr thr_suspend system call. If the thread is not suspended at the time of the .Nm call, the wake is remembered and the next attempt of the thread to suspend itself with the .Xr thr_suspend 2 results in immediate return with success. Only one wake is remembered. .Sh RETURN VALUES .Rv -std thr_wake .Sh ERRORS The .Fn thr_wake operation returns these errors: .Bl -tag -width Er .It Bq Er ESRCH The specified thread was not found or does not belong to the process of the calling thread. .El .Sh SEE ALSO .Xr ps 1 , -.Xr thr_self 2 +.Xr thr_self 2 , .Xr thr_suspend 2 , .Xr pthread_cancel 3 , .Xr pthread_resume_np 3 , .Xr pthread_suspend_np 3 .Sh STANDARDS The .Fn thr_suspend system call is non-standard and is used by .Lb libthr to implement .St -p1003.1-2001 .Xr pthread 3 functionality.
