------
win32Trace(x) - Trace macro. Use double in parenthesis for x. Same args as printf.
win32ASSERT(x) - assert macro, but will not abort program and output sent to trace routine.
win32APICALL(x) - Use to enclose a Win32 system call that should return TRUE.
win32APICALL_HANDLE(h,api) - Use to enclose a Win32 system call that should return a handle.
