_LWP_KILL(2)              NetBSD System Calls Manual              _LWP_KILL(2)


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 spe- cific 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] sig is not a valid signal number. [ESRCH] No LWP can be found in the current process corresponding to that specified by lwp.
