Leopard Technical Q&As: Legacy Documents
Legacy documents consist of guides, references, sample code, and other resources that have become irrelevant for current product development. Some of these documents describe features, functions, classes, or methods that are no longer supported. Other legacy documents describe currently supported technologies, but the approaches and development techniques described in these documents are no longer recommended.
Go to the Hardware & Drivers Technical Q&As for up-to-date development information.
