_lwp_kill(2)							   System Calls 						      _lwp_kill(2)

NAME

       _lwp_kill - send a signal to a LWP

SYNOPSIS

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

       int _lwp_kill(lwpid_t target_lwp, int sig);

DESCRIPTION

       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 signal.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.

RETURN VALUES

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

ERRORS

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

       EINVAL	       The sig argument is not a valid signal number.

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