83 * - GET_WINDOWS_FUNCTION_PP allows "name" to be redirected via

85 * intended for the ANSI/Unicode DoSomething/DoSomethingA/DoSomethingW.
86 * If your function has an argument of type "LPTSTR" or similar, this

88 * (However, it can't always be used, as it trips over more complicated
89 * macro trickery such as the WspiapiGetAddrInfo wrapper for getaddrinfo.)
