Interface
The Windows interface is arranged as forty structures containing several hundred functions.Generally the functions take the same arguments and return the same result types as the corresponding function in C but there are some differences to reflect the differences in the type systems.Many objects, such as windows and fonts, are represented by handles, e.g. HWND and HFONT. Frequently functions in C take an integer argument with constants defined.Datatypes are used for these in ML where possible. Where in C several options can be or-ed together in ML a list of a datatype is used.
