2 What is the DCL?
Escale is a sample code based on the Desktop Connection Library, DCL for short. This library is a framework that replaces Apple's Desktop Integration Libraries. Like the DILs, the DCL is aimed to be targetted on several platforms, although it currently only builds for MacOS X since this is what we use.
Unlike the DILs, the DCL uses modern technologies built into MacOS X, especially the Unix foundations. The DCL is completely threaded using POSIX threads (there is minimal support for MacOS legacy threads as well) and uses as little CPU as possible.
For more information on the DCL, please refer to the forthcoming DCL programmer reference.
