TQAGetPtr

A drawing engine must define a method to get a pointer value of a draw context state variable.

typedef void *(*TQAGetPtr) (
                            const TQADrawContext *drawContext, 
                            TQATagPtr tag);

drawContext

A draw context.

tag

A state variable tag.

DESCRIPTION

Your TQAGetPtr function should return, as its function result, the pointer value of the draw context state variable specified by the drawContext and tag parameters. If you do not recognize or support the specified tag, your TQAGetPtr function should return the value 0.
