_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 tar‐
get_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 sig‐
nal), 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.
