How to get the OS X system version?

Question

I want to get the OS X system version, such as: 10.5.4, 10.4.8, etc. I want to get it in my app, how do I do this? Thanks!

Again, you can use Gestalt. Look at the documentation for more information; specifically, you'll want to pass the gestaltSystemVersionMajor, gestaltSystemVersionMinor, and gestaltSystemVersionBugFix constants in the "System Version Constants" portion of the Gestalt Manager Reference documentation
