            Bug ID: 216951
           Summary: close_range(2) page missing; closefrom(2) needs
                    refreshing for glibc inclusion
           Product: Documentation
           Version: unspecified
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: man-pages
          Assignee: documentation_man-pages@kernel-bugs.osdl.org
          Reporter: sam@gentoo.org
        Regression: No

This came up at
https://github.com/OpenRC/openrc/pull/541#discussion_r1070724653.

man-pages currently doesn't document closefrom(2) at all, and is outdated wrt
close_range(2) (it only covers the kernel uapi interface, not the fact it's in
glibc & the relevant headers - in since glibc 2.34.).

Hi Sam!


I would appreciate a patch from someone experienced in these APIs to the
mailing list, according to ./CONTRIBUTING.  Maybe you can summon someone
by CCing in the mailing list?

Cheers,
Alex

Shouldn't it be closefrom(3)?  There's no closefrom syscall — Glibc
implements it using close_range (if available).
