BOOL GpiQueryDefViewingLimits(hps, prclLimits)
HPS hps;              /* presentation-space handle               */
PRECTL prclLimits;    /* pointer to structure for viewing limits */
 
The GpiQueryDefViewingLimits function retrieves the default viewing limits.
The default viewing limits define the values given to a presentation space's
viewing limits whenever that presentation space is reset. (The viewing
limits specify a rectangle in model space that the system uses to clip
output.) A presentation space can be reset by using the GpiResetPS
function.

            the default viewing limits.
