DTHandlerInit(

  Function Description:

      Fills in the given HandlerFuncTable with pointers to all the
      appropriate handler functions, based on notification code.

  Arguments:

      HandlerFuncTable -- an uninitialized array of pointers of type
      LPFNDTHANDLER, which point to handler functions (see handlers.h)

      NumEntries -- the number of entries in the array.  Currently
      only used to zero out the array.

  Return Value:

      Always returns TRUE.

  Note:

      This comment applies to all DTHandler_xxxx functions.

  Function Description:

      For the present, each handler function simply adds "xxxx
      called." to the end of the string passed in, and calls
      DTTextOut to output the whole string to the Debug Window.  This
      allows handler functions to be disabled easily, or to output
      more information (like the arguments) via multiple calls to
      DTTextOut, etc.  See the Debug/Trace documentation for more
      information.

  Arguments:

      vl -- Variable used to strip arguments off the stack of
      WSA[Pre|Post]ApiNotify, the calling function.

      ReturnValue -- A void pointer to the return value for the
      original API/SPI function.  Use a local variable to cast it to
      the appropriate type.

      LibraryName -- For API functions, this should just be
      "WinSock2", but for SPI functions it is the name of the service
      provider.  This is to distinguish among the multiple service
      providers that WinSock2 may be calling.

      Buffer -- A string containg some info about the thread and
      function call # of this call.

      Index -- How many characters are in the above.

      BufLen -- How big is the buffer.

      PreOrPost -- TRUE if called by a WSAPreApiNotify, FALSE if
      called by WSAPostApiNotify.

  Return Value:

      If the PreOrPost argument is FALSE, then the return value is
      ignored.  If it's TRUE, then the return value indicates to
      WSAPreApiNotify whether or not we want to short-circuit the API
      or SPI function.  TRUE means short-circuit it, FALSE mean don't.
