macOS identifying libc version

[info1686]

Hello,
How do I find out which version of libc is installed on my Mac machine?

I have a Mac OS X 10.4 x86 server.

Does the default libc version change from one Mac release to another?

Thanks in advance...

Doesn't look like there is a specific 'version' attached to libc in OS X beyond what the major OS version is. I wouldn't be surprised if the OS X libc is based on FreeBSD's, but contains differences from time to time.

If you need libc behavior based on a specific version of OS X, base it on the version of OS X in which it appears.
