Details

Summary

I'd like to add an option to display fmt.
Before doing so, make a function for displaing info for ease of refactoring.
Added kyua test cases.

Test Plan

% make install, etc...
% kyua test -k /usr/tests/Kyuafile sbin/sysctl

i is assigned but not used. I think it's quite likely that this sysctl call would always succeed as buf is sufficiently large, so if I was you I'd check the return value or maybe convert it to an assertion here.

Looking at how another sysctl failure is handled, it silently skips printing. I suppose this is for -a, all option.

I will follow the same error handling.

  • Return error code from show_info()
  • Update error description of show_info()
  • systat: Added -F option to show "fmt"

Have you run mandoc -Tlint and igor on the manual page?

At the very least, the latter would hint that you need to bump .Dd :)

Also, I'm not sure "structured" is the best word. Maybe "compound"?

  • Bump the date, use "struct" as referenced in other parts of man sysctl, and give few examples of struct types.

No, I hadn't known.
Thanks for the info and I had ran.

I didn't realize your suggested changes in the first round of changes.

When I looked at lower pages of sysctl.8, I found 'struct' and used it.
You seemed to question about "structured" and didn't pick up this time. If "structured" is a better word, I don't have an object against it.

Manual page language looks good to me. Can't speak about source code or consistency between them.

No, "struct" is fine for consistency, I think.

  • sysctl -l to display the lenth of returned data.
bcr added a subscriber: bcr.

Confirm man page looks good.

This all looks good to me. Addition of tests is helpful and appreciated.

I think "size" (in bytes?) is more accurate than "length".

error is always 0, can we get rid of either error or i?
