    TITLE  :  Abbreviated DLL Generation Procedure




  Below  is  all  the  code  and information necessary to create  a
  Dynamic Link Library file using Borland C++ 2.0  for  Windows. It
  includes a sample C source file as well as the  module definition
  file  (.DEF).    Instructions on how to configure Borland C++ 2.0
  and compile the C source code is also listed below.   Please note
  this  is  the  bare minimum amount of code needed to create a DLL
  file  and will actually do nothing if loaded  by  a  Windows  EXE
  file.

  //...............................................................
  // DLLTEST.C -- notice we have a LIBMAIN function instead of
                  WINMAIN

  #include <windows.h>  // Include the Windows function prototypes

  int FAR PASCAL LibMain(HANDLE hInstance, WORD wDataSeg,
                         WORD wHeapSize, LPSTR lpszCmdLine)
  {
      // Any code that needs to be executed only once when the
      // DLL gets loaded by Windows goes here.

      return 1;               // Success (or 0 for Failure)
  }

  int FAR PASCAL WEP(int nParameter)
  {
      return 1;
  }

  //...............................................................
  // DLLTEST.DEF -- notice we have a LIBRARY  statement  instead of
  //                  EXETYPE as well as a DATA statement ending in
  //                the word SINGLE.

  To compile the test .DLL file type:
      BCC -WD dlltest.c  <enter>

  //................................................................

  Make sure that  Borland  C++  2.0  is  in your path prior to both
  Microsoft C and any earlier version of Turbo C++.

    Example: path=c:\dos;c:\borlandc\bin;c:\xtgold;c:\tc\bin

  //................................................................

  Make sure the TURBOC.CFG file being used has the correct  path to
  both library and include files.

      Example:
          -Ic:\borlandc\include
          -Lc:\borlandc\lib
