RE: Detecting OS loader lock

Hi Christoph,

Internally, OS loader lock is maintained in the PEB. But, we should not
look at the loader lock value in the PEB, not even for debugging purposes,
and especially not in libraries which might be reused.

In general, making any assumptions about undocumented system state is a
recipe for app compat problems down the line.

The recommended way is using AppVerifier. AppVerifier has checks that make
sure DLLs aren't doing anything wrong in DllMain. I think you can also run
with these checks on when running from Visual Studio with AppVerifier.
There's also a whitepaper on DLL best practices at
http://download.microsoft.com/download/a/f/7/af7777e5-7dcd-4800-8a0a-b183365
65f5b/DLL_bestprac.doc.

Hope this helps.

Best regards,
Jeffrey Tan
