new operator in DllMain of MFC Extension Dll

Hi,

Dll best practices document from Microsoft available at MSDN recommends avoiding use of memory management function from the dynamic C Run-Time (CRT) within DllMain. But DllMain function of MFC Extension DLL is dynamically allocating the memory for CDynLinkLibrary in the code snippet available at MSDN "http://msdn.microsoft.com/en-us/library/1btd5ea3%28v=VS.80%29.aspx".

Is it a violation of Dll Best Practices or ok to use in MFC extension DLL?

thanks

It does seem contradictory. But what you have to realize is that DllMain isn't the true entry point...

So when the linker is resolving symbols for your DLL, it will find "_DllMainCRTStartup" in the LIB for your CRT. Allowing the CRT to do what it needs to do before calling your DllMain.

So I suppose it's safe to assume that "new" doesn't do anything "bad" while being called from DllMain. On the other hand, there's nothing stopping you from not doing that either - just export DllStartup/DllShutdown symbols and require users to call them before/after using your dll.
