_LWP_KILL(2)                  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
     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]  sig is not a valid signal number.

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

SEE ALSO
