Open32
Open32 API enables the migration of Windows applications to OS/2 by providing a subset of the Win32 APIs on OS/2 for source code compatibility. The Open32 API provides an identical interface as the function in the Win32 environment.
In "Open32 Developer API Extensions for OS/2 Warp" Redbook from IBM is clarified that Open32 is not a Win32 API emulation, it is a native OS/2 function that is built on the operating system just like other interface layers like GPI, Presentation Manager, Control Program, etc.
The OS/2 Warp Version 3.0 Toolkit includes the required Open32 headers and libraries.
The following tools can be used to to analyse and migrate Windows code to OS/2 code:
- SMART Version 2.1B
- IBM Hyperwise Lite
- IBM VisualAge C++ for OS/2 Version 3.0
