Is this C++?

Sigh.

I have a webcam that doesn't work under linux so I've decided to write a driver for it. I started reading an article demoing the process and right away ran into this:

Code:

static struct usb_driver led_driver = {
	.owner =	THIS_MODULE,
	.name =		"usbled",
	.probe =	led_probe,
	.disconnect =	led_disconnect,
	.id_table =	id_table,
};

which if this is C++ my project just became more difficult, because some form of this struct is necessary.

It is a gcc extension to name the fields of a struct for the elements, rather than just putting the fields in the order they appear in the original struct.

It should work just fine in C, as long as you are using gcc - which you probably will do in Linux.

It's standard in C99.

Not sure if the Microsoft compilers adopted it or not.
