That's C++ not C though.
Just thought I'd point that out as I thought "I've never seen that before", and now I know why (I don't know C++).
I want to point out that this is still C. The person you are replying to simply used a C++ reference site.

On the above linked page you will also see, among other information, what standards this conforms to: C89, C99, POSIX.
The reason you might not have encountered it would be it's not considered a beginner tool, i.e. it's reasonable you will write entire programs without it. I'm sure it's most common use is in the debugging area.
I see, right, thanks for that correction.
