/*
**  FILLPROTUP -- fill the protection tuple from pipe.
**
**	This routine is broken off from d_prot.c so that we
**	don't get symbol table overflows.
**
**	Parameters:
**		protup -- pointer to the protection tuple to fill.
**
**	Returns:
**		A bool telling whether we have PERMIT ALL TO ALL
**		permission.
**
**	Side Effects:
**		The R_up pipe is flushed.
**
**	History:
**		4/16/80 (eric) -- broken off from d_prot for 6.2/10.
