Winamp Software Development Kit
In this section of NSDN, we show you how to access Winamp's functionality through external applications. If any of you wanted to build a can opener that ran Winamp, you would need the information provided here. API functions and other code snippets are available in the C/C++ programming language. Needless to say, a programming background is helpful. We strongly suggest joining the Winamp Development Forum for all levels of Winamp development. A better support community simply does not exist.
