Copy to dev/null windows

Privacy policy. You might install a "null driver" that is, nonexistent driver for a device if the device is not used on the machine and should not be started. Such devices do not typically exist on a machine, but if they do, you can install a null driver. Additionally, the system installs null drivers for devices that do not have a function driver , if they are capable of executing in raw mode. The hardware ID for the device in the Models section should identify the device specifically, using the subsystem vendor ID and whatever other information is relevant.

The operating system will create a device node devnode for the device, but if the device is not capable of executing in raw mode, the operating system will not start the device because a function driver has not been assigned to it.

CoDEmanX: That's not my experience. Writing to the console - or even a file - can take a significant chunk of time.

I've just tested it with a program writing "Hello there" to stdout times. Redirecting to a file on an SSD took 18 seconds. Redirecting to NUL took 4 seconds.

Not redirecting at all made me give up through a lack of patience after a while That makes more sense. So nevermind my question and thanks for helping : — user Add a comment. Active Oldest Votes. Improve this answer. Short answer is no, it doesn't work.

Now, you can test it: open two terminal in your system. Archemar Archemar Well, sure, it's physically possible, but if a system erases data when told to copy it, it's severely broken.
