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 // 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

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

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
