cc -mt [ flag... ] file...[ library... ]
#include <signal.h>
#include <thread.h> int thr_kill(thread_t thread, int sig); |

thr_kill() sends the sig signal to the thread designated by thread. thread must be a member of
the same process as the calling thread. sig must be one of the signals listed in signal(3HEAD); with the exception of SIGLWP, SIGCANCEL, and SIGWAITING being reserved and off limits to thr_kill(). If sig is 0, a validity check is done for the existence of the target
thread; no signal is sent.

Upon successful completion, thr_kill() returns 0. Otherwise, an error number is returned. In the event of failure, no signal is sent.
