 * Ansi - Unicode thunking.
 *
 * Unicode or Ansi-only apps can call the avifile APIs.
 * any Win32 app who wants to use
 * any of the AVI COM interfaces must be UNICODE - the AVISTREAMINFO and
 * AVIFILEINFO structures used in the Info methods of these interfaces are
 * the unicode variants, and no thunking to or from ansi takes place
 * except in the AVIFILE api entrypoints.
 *
 * For Ansi/Unicode thunking: for each entrypoint or structure that
 * uses chars or strings, two versions are declared in the Win32 version,
 * ApiNameW and ApiNameA. The default name ApiName is #defined to one or
 * other of these depending on whether UNICODE is defined (during
 * compilation of the app that is including this header). The source will
 * contain ApiName and ApiNameA (with ApiName being the Win16 implementation,
 * and also #defined to ApiNameW, and ApiNameA being the thunk entrypoint).
