Unloads any DLLs that are no longer in use, probably because the DLL no longer has any instantiated COM objects outstanding.
Note This function is provided for compatibility with 16-bit Windows.
Syntax
void CoFreeUnusedLibraries();
Return value
None
Remarks
Applications can call CoFreeUnusedLibraries periodically to free resources. It is most efficient to call it either at the top of a message loop or in some idle-time task. CoFreeUnusedLibraries internally calls DllCanUnloadNow for DLLs that implement and export that function.
