Getting the current process creation time in Linux

How do I get the cur开发者_StackOverflow中文版rent process creation time using c/c++ on Linux? When I'm opening the file /proc//stat

The output is just a bunch of numbers. How do I know which one of them is the creation time?

The manpage lists the order and meaning of the values of /proc/[pid]/stat. This answer more information.

I suggest you look into man 5 proc. On my system, the 22nd entry is the start time.
