I have C plus CPS code that would really benefit from knowing when there is
no input waiting  on PostScriptInput (ie. all the current cps commands from
the NeWS server have been handled).  One application involves holding a
repaint request until all other current requests (user input) have been
handled.
Could someone please tell me how to do this?  I am using a sun4-110 with
OS4.01?
From my search of the manuals I gather that using SYSTEM V reads might
solve
the problem although I haven't really studied the details.  Of course, the
CPS
calls use regular io.

Any light that can be shed on this topic would be very much appreciated.

Thanks
