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

_lwp_kill( ) 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(5). 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

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

ERRORS

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

EINVAL

sig is not a valid signal number.

ESRCH

target_lwp cannot be found in the current process.
