_lwp_kill(2)				   System Calls 			     _lwp_kill(2)

       _lwp_kill - send a signal to a LWP

       #include <sys/lwp.h>
       #include <signal.h>

       int _lwp_kill(lwpid_t target_lwp, int sig);

       The  _lwp_kill()  function  sends  a signal to the LWP specified by target_lwp. The signal
       that is to be sent is specified by sig and must	be  one  from  the  list  given  in  sig-
       nal.h(3HEAD).  If sig is 0 (the null signal), error checking is performed but no signal is
       actually sent. This can be used to check the validity of target_lwp.

       The target_lwp must be an LWP within the same process as the calling LWP.

       Upon successful completion, 0 is returned. A non-zero value indicates an error.

       If any of the following conditions occur, _lwp_kill() fails and returns the  corresponding

       EINVAL	 The sig argument is not a valid signal number.

       ESRCH	 The target_lwp argument cannot be found in the current process.
