The problem here I suspect is that the proper prototype is not included in
the current set of Win32 API headers. So, you may have to go to the
Windows32/Functions.h and ASCIIFunctions.h and UnicodeFunctions.h and add
the prototypes and defines. By looking at winmm.def it looks like you will
need to to the ASCII/Unicode thing for this function, and also it looks like
they are prototyped WINAPI (or STDCALL). Strangely enough I can't seem to
find mciSendString in any of my documentation, but that may be because I
only have docs for the core API.
