(DoesExeFileContainZip is a red herring from Process Explorer. It is just the nearest named/exported function in dopuslib.dll to the code Process Explorer is interested in. The offset Process Explorer reports is probably a large number, putting the code well outside of DoesExeFileContainZip itself, but Process Explorer has no info on any nearer functions so that's the best it can do. It will report most of the DLL as being DoesExeFileContainZip plus some offset.)
