GXLoadTag

You can use the GXLoadTag function to load a tag into memory.

void GXLoadTag(gxTag target);

target

A reference to the tag object to be loaded into memory.

DESCRIPTION

The GXLoadTag function moves a tag object from disk storage to the active graphics client heap of your application. When you or QuickDraw GX unload a tag object from memory to disk storage using the GXUnloadTag function, QuickDraw GX creates a 4-byte stub that remains in the graphics client heap. When you use the GXLoadTag function to retrieve the stored object, QuickDraw GX obtains the location of the stored tag object from the stub.
