/*
**  SEND_OFF -- send a call off to another process
**
**	This routine sends a call off to the process indicated
**	ppb->pb_proc.  It also sends parameters pc & pv.  It
**	just sends it, and does not wait for a response.
**
**	WARNING:
**		The pipe buffer is not flushed after putting out
**		the call; this must be done by the caller.
**
**	Parameters:
**		ppb -- a pointer to a pipe block which is used
**			as the I/O area, and also identifies
**			the target process.
**		pc -- the parameter count.
**		pv -- the parameter vector.
**
**	Returns:
**		none
**
**	Side Effects:
**		none
**
**	Trace Flags:
**		11.0 - 11.7
