_lwp_kill -- send a signal to a light-weight process
Standard C Library (libc, -lc)
_lwp_kill(lwpid_t lwp, int sig);
_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
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
Signals will be posted successfully to suspended LWPs, but will not be
handled further until the LWP has been continued.
The _lwp_kill() function returns the value 0 if successful; otherwise the
value -1 is returned and the global variable errno is set to indicate the
[EINVAL] sig is not a valid signal number.
[ESRCH] No LWP can be found in the current process correspond-
ing to that specified by lwp.
