CauseWay provides an API for C and assembly language programmers as an extension of the DPMI API via INT 31h. Including the file CW.INC allows easy access to this API through appropriately named functions. You may also call the CauseWay API directly with appropriate register setup.
CauseWay also provides all of the DPMI 0.9 API services on systems without a true DPMI server.
