Re: More about packaging (fwd)

As far as I know:

Multiple DLL usage within the same process goes to same DLL instance.   
Needs as many frees as there have been loads.

Other processes will see their own instance (code pages etc. shared of  
course), unless the DLL uses inter-process data sharing.

dllproc/base/freelibrary.asp

dllproc/base/process_and_thread_functions.asp

ps.
What's the real usage/need scenario for the unloadlib?  Server apps or  
something (plugin stuff) is the only place where I could see it being  
really needed.
