INF: Changes to DLL Makefiles for Windows NT 3.1 Release

PSS ID Number: Q101337 Article last modified on 04-20-1994

3.10 WINDOWS NT

The information in this article applies to:
- Microsoft Win32 Software Development Kit (SDK) for Windows NT, version 3.1

SUMMARY

The documentation and sample makefiles for beta versions of the Win32 software development kit (SDK) use a different entry point for dynamic-link libraries (DLLs) than is recommended for the Windows NT 3.1 release. This difference is especially important to note if your DLLs are linked with the C Run-time. Previously, Microsoft recommended calling _crt_init() in your DLL entry point (or making it the DLL entry point), so that the C run time would be correctly initialized. Currently, Microsoft recommends that all DLLs provide a main function BOOL WINAPI DllMain( HANDLE hDLL, DWORD dwReason, LPVOID lpReserved ) and that the entry point be specified with the following linker option: -entry:_DllMainCRTStartup$(DLLENTRY)

MORE INFORMATION

The loader calls DllMainCRTStartup(), which is provided in the C Run-time library. This routine handles all C Run-time and C++ initialization, then determines whether DllMain() is exported from the DLL, and executes it if it exists.
