The signal that is to be sent is specified by \fIsig\fR and +must be one from the list given in \fBsignal.h\fR(3HEAD). If \fIsig\fR is 0 +(the null signal), error checking is performed but no signal is actually sent. +This can be used to check the validity of \fItarget_lwp\fR. +.sp +.LP +The \fItarget_lwp\fR must be an LWP within the same process as the calling LWP. +.SH RETURN VALUES +.sp +.LP +Upon successful completion, \fB0\fR is returned.
