DESCRIPTION

thr_kill() sends the signal, sig, to the thread specified by target_thread. target_thread must be a thread within the same process as the calling thread.  sig must be one from the list given in signal(5).  If sig is zero, error checking is performed but no signal is actually sent.  This can be used to check the validity of target_thread.

RETURN VALUES

Zero is returned when successful.  A non-zero value indicates an error. 

ERRORS

If any of the following conditions detected, thr_kill() fails and returns the corresponding value:

EINVAL sig is not a valid signal number.
