_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.
