Free layer software for windows

An open source SDK for plugin development. The SPL (Simple Plugin Layer) library was designed to be an open source SDK for plugin development.
With SPL you can extend every application written in C/C++ to use your own plugins, SPL will do all the managing, loading and unloading stuff for you. Additionally, the whole framework is fully multi-platform capable, so you dont have to develop multiple versions of the same plugin for platforms provided by SPL.
Main features:
- Open Source, uses LGPL license
- Free, costs absolutely nothing, even for commercial use
- Platform independent architecture
- Implementations for Linux, Solaris 8 and Win32 available, more platforms coming soon ...
- Documentation in various formats, powered by Doxygen
- Optional macros for fast and easy plugin development
- Variable plugin arguments for extensible APIs
- Thread-safety for complex applications
- Uses STL library for stable and portable containers
- Object-oriented design, easy to extend
- Customizable to 32- or 64-bit systems
- Completely written in C++, no other dependencies except STL needed
- Buildable as static/shared library or DLL (only Win32)
- Various examples for all platforms explaining the development step by step
- Source code written in uniform style
System requirements:
- Microsoft Visual Studio 6.0
- Microsoft Visual Studio 2002
- Microsoft Visual Studio 2003
- Microsoft Visual Studio 2005

a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware Simple DirectMedia Layer was designed to be a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer.
