On my pc with debian 11 installed, I only have sections 1 to 9 of the manual. However on the online linux manual there's also a section 0p containing the C header files, in which I am interested: is it possible to install section 0p locally?

The wikipedia page (https://en.wikipedia.org/wiki/Man_page#Manual_sections) says "On some systems some of the following sections are available:", including section 0, but I wonder what it means by "on some systems", if it means that you don't have them by default or that you can't even install them later.

The 'p' in there refers to POSIX. On Debian and other Debian-based distros such as Ubuntu, the POSIX header man pages are provided by the manpages-posix-dev package (and they are in section 7).
