NAME
_lwp_kill —
send a signal to a
light-weight process
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <lwp.h>
int
_lwp_kill(
lwpid_t
lwp,
int sig);
DESCRIPTION
_lwp_kill() sends the signal specified by
sig to the light-weight process specified by
lwp. If the
sig argument is given
as 0 (zero),
_lwp_kill will test for the existence of the
target LWP, but will take no further action.
Job control signals and uncatchable signals can not be directed to a specific
LWP: if posted with
_lwp_kill, they will affect all LWPs in
the process.
Signals will be posted successfully to suspended LWPs, but will not be handled
further until the LWP has been continued.
RETURN VALUES
A 0 value indicates that the call succeeded. A -1 return value indicates an
error occurred and
errno is set to indicate the reason.
ERRORS
-
-
- [
EINVAL

number.

- [
ESRCH
]
- No LWP can be found in the current process corresponding to
that specified by lwp.
