The OS/2 API Project

The OS/2 API Project (also known as The OS/2 API Documentation Project) is an effort that aims to document all the OS/2 available APIs under an non-restrictive license that can allow derivative works.

For contributors, please review the Introduction to the OS/2 API Documentation.

OS/2 Warp APIs

This are the APIs included on the IBM's OS/2 Warp product.

OS/2 Ported APIs

These are APIs ported from other platforms to OS/2-eCS-ArcaOS. The functions documentation of the APIs are only linked to their respective sites.
