NAME

_lwp_kill − send a signal to a LWP

SYNOPSIS

#include <sys/lwp.h>
#include <signal.h>

int _lwp_kill(lwpid_t target_lwp, int sig);

DESCRIPTION

_lwp_kill() sends a signal to the LWP specified by target_lwp. The signal that is to be sent is specified by sig and must be one from the list given in signal(5).  If sig is 0 (the null signal), error checking is performed but no signal is actually sent.  This can be used to check the validity of target_lwp.

The target_lwp must be an LWP within the same process as the calling LWP. 

RETURN VALUES

Zero is returned when successful.  A non-zero value indicates an error. 

ERRORS

If any of the following conditions occur, _lwp_kill() fails and returns the corresponding value:

EINVAL sig is not a valid signal number. 

ESRCH target_lwp cannot be found in the current process.
