NAME_lwp_kill — send a signal to a light-weight process
LIBRARYStandard C Library (libc, -lc)
_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 VALUESA 0 value indicates that the call succeeded. A -1 return value indicates an error occurred and errno is set to indicate the reason.
- sig is not a valid signal number.
- No LWP can be found in the current process corresponding to that specified by lwp.
HISTORYThe _lwp_kill() system call first appeared in NetBSD 5.0.
