CoFreeUnusedLibraries function (combaseapi.h)

  • Article

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.
