DisposeRgn

Deallocate memory used to store a Region

#include <Quickdraw.h> Quickdraw

void DisposeRgn(theRgn );

RgnHandle theRgn ; region to eliminate

DisposeRgn frees all memory associated with a region-its master pointer

and the RAM containing the variable-length Region structure. Use this only

when you are completely finished with the region.

theRgn is the handle of the region to dispose.

Notes: After using this function, the value of theRgn (the region handle) is

meaningless. Be sure NOT to use the region handle again, unless you create a

new Region structure and assign it to theRgn via NewRgn.

Use SetEmptyRgn if all you want to do is reinitialize a region handle to

point to an empty region.

See CloseRgn for an example of usage.
