When a managed DLL makes a call to an unmanaged DLL what controls the
lifetime of the unmanaged DLL? I am assuming when I make the first call to
an unmanaged DLL, the unmanaged DLL is loaded into memory and stays in memory
(meaning global variables are maintained). How does to unmanaged DLL know
when to unload? Are there any technical articles that discuss this?
