Detect when a Module (DLL) is unloaded

Question

Is there a way to progammatically detect when a module - specifically a DLL - has been unloaded from a process?

I don\'t have the DLL source, so I can\'t change it\'

Answer 1

One very bad way(which was used by starcraft 2), is to make your program attach to itsself then monitor for the dll unload debug event(http://msdn.microsoft.com/en-us/library/ms679302(VS.85).aspx), else you'd either need to IAT hook FreeLibrary and FreeLibraryEx in the process or hotpatch the functions in kernel32 them monitor the names being passed and the global reference counts.
