_getviewcoord Functions
 Summary Example                         Up Contents Index Back
────────────────────────────────────────────────────────────────────────────
 
     The _getviewcoord functions translate the specified coordinates
     (<x>, <y>) from one coordinate system to view coordinates and
     return them in an xycoord structure (defined in GRAPH.H).
 
     The _getviewcoord_w and _getviewcoord_wxy routines are
     implemented as macros.
 
     The various _getviewcoord functions translate in the following
     manner:
 
     Function              Translation
 
     _getviewcoord         Physical coordinates (<x>, <y>) to view
                           coordinates
 
     _getviewcoord_w       Window coordinates (<wx>, <wy>) to view
                           coordinates
 
     _getviewcoord_wxy     Window coordinates structure (<pwxy1>) to
                           view coordinates
 
     NOTE: In Microsoft C version 5.1, the _getviewcoord function was
           called _getlogcoord.

     Return Value
 
     The _getviewcoord functions return the coordinates as noted above.
     There is no error return.
