Xcode 8: C-API Documentation?

Is there a documentation-set I can install in Xcode 8 to get back BSD Library Functions documentation?

In Xcode 7 and all the way back to Xcode 4 I was able to lookup documentation for BSD Library Functions from within Xcode in quick help. I.e. functions such as printf, vprintf, pthread_create etc. It appears the documentation for all BSD Library Functions has been removed. Sometimes we do need to call plain old C-functions and it was very useful to have this documentation in Xcode in quick help.

You might still be able to open up a Terminal window and type in a "man" or "man 3" command to see the *nix man pages for BSD library function.
