The C application programming interface (API) enables to embedd CSS in your own application as a macro language or write your own libraries for CSS. The C API uses the standard linkage of the system (__stdcall for Windows, _System for OS/2) so in fact every compiler should be able to use it. However for compilers not listed below there are usually some modifications necessary in the header file KCssC.h. In case the object format differs from microsoft, a new LIB file must be created by a tool like IMPLIB. Below you find the list of currently tested compilers. If you have adapted and tested another successfully, please let me know.
