You can use the GXUnloadShape function to unload a shape from memory.

void GXUnloadShape(gxShape target);

target

A reference to the shape object to be unloaded from memory.

DESCRIPTION

The GXUnloadShape function moves a shape object from the active graphics client heap to disk storage. When you or QuickDraw GX use the GXUnloadShape function to unload a shape object from memory to disk storage, QuickDraw GX stores its location in a 4-byte stub in the active graphics client heap. When you use the GXLoadShape function to reload the object from disk storage to memory, QuickDraw GX uses the stub to find the stored shape object.
