Read linux kernel version using C?

Question

I am using Ubuntu and I want to read the version of its kernel. I found a file named version in /proc/ that records the version of the current kernel.

If I dont want to read file, is there any other way, like built-in function in C, that I can read the version in C?

Thanks

Answer 1

You can use the uname() system call.

Answer 2

Check the uname function. It gives you a lot of information without the need to parse output of some linux executables.
