18The SDL Falcon Module.

This is the base of the falcon SDL subsystem. The SDL library can be found at http:www.libsdl.org.

Forewords

The SDL Falcon module tries to stick with SDL interface and conventions whenever possible. However, in some cases where Falcon programming language provides structures and solutions that are better suited to perform certain tasks, the interface may diverge from the original one.

The most significative case is the SDLSurface class and its derived classes that encapsulate many of the SDL operations that are menat to be performed on surfaces and screens.

Also, event structures are not directly exposed to the Falcon programs; instead, they are reported through callbacks. In fact, callbacks and parameter expansion is several time faster than the creation of a Falcon object that should be then inspected and eventually marshalled.
