How enumerate all device objects?

Question

Sorry for my English. I want to enumerate all pointers to the DEVICE_OBJECT's in the system. I know that this can be done from the user mode, but I forgot. May be with helping of ZwQueryDirectiryObject or SetupAPI..?

Answer 1

You can use NtQueryDirectoryObject , but that doesn't give you pointers to the DEVICE_OBJECT s. Try opening the device objects and then enumerating handles using NtQuerySystemInformation to get the pointers.
