I'm running Ubuntu 12.04. I had Fedora a couple of years back and I saw the man pages for the following there:

standard typedefs (suffixed by "_t") etc.

I tried this:

man unistd

But it didn't find it.

I think those pages are not there in Ubuntu.

Although man stdio works and other man pages are there.


  • If Ubuntu doesn't have those pages, please tell me how to download them
  • And what is the command for viewing standard typedef man page i.e. man page for size_t, pid_t, off_t, clock_t etc.

I tried man stddef but it says "command not found".

This is what needed to do...

sudo apt-get install manpages-posix-dev

to get those pages :)
