assert not dll in os.listdir(os.getcwd()) # Ensures that the DLL will not false-positive load because it's in the current working dir | |
loaded_dll = WinDLL(dll) # Attempt to load DLL. If the DLL is not on PATH or in os.getcwd() it will raise a WindowsError | |
FreeLibrary(loaded_dll._handle) # if successful, we should be good neigbors and unload it | |
del loaded_dll # completely rid of the memory instance |
