GetClip

void GetClip(curClip );

RgnHandle curClip ; becomes a handle to the current clipRgn

GetClip is used to obtain a copy of the current clipping region.

curClip is a RgnHandle, normally to an empty Region created by NewRgn.

Upon return, the RgnHandle's master pointer is changed to point to a

copy of the clipping region of the current GrafPort.

Notes: GetClip is typically used as the first step in making a temporary change

to the clipping region. For instance,

saveClipRgn = NewRgn(); /* get an empty region */

GetClip( saveClipRgn ); /* save current */

SetClip( myClipRgn ); /* install desired clipRgn */

/*... ( draw a figure ) ... */

SetClip( saveClipRgn ); /* restore previous value */

DisposeRgn( saveClipRgn ); /* not needed any more */
