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.
On "Open32 Developer API Extensions for OS/2 Warp" Redbook by 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.
