Are man page sections 2 and 3 available in macOS Mojave? Are the system calls (section 2) and library class (section 3) of the man pages available in macOS Mojave? I recently upgraded from an ancient MacBook Pro running OS X El Capitan and they aren't installed with Xcode, and I haven't found anything on how to get them installed.
The manpages are installed with the command line tools. When I get a chance, I’ll edit the exact location to install from inside XCode. But, yes, there are manpages for sections 2 and 3, in Mojave.
