Man page update is not done yet.
Not tested.
I am not sure what __POSIX_VISIBLE guard is appropriate for the function.

| 92 ↗ | (On Diff #80395) | It was added in POSIX 2008 so you can add this to xlocale/_string.h where the other _l functions are declared. |

Some native English speaker should review the man page changes. Some sentences don't sound right to me but I'm no native speaker either. Everything else looks good to me.
| lib/libc/string/strerror.3 | ||
|---|---|---|
| 76 | Maybe: .Fn strerror is not thread-safe. It returns a pointer to an internal buffer that could be overwritten by a .Fn strerror call from another thread. (.Nm or .Fn as appropriate) | |
| 83 | Maybe The .Fn strerror_l function accepts error number and locale arguments and returns a pointer to a string corresponding to the specified error in the given locale. .Fn strerror-l is thread-safe. | |
| lib/libc/string/strerror.3 | ||
|---|---|---|
| 170 | Add .Fn strerror_l here as well? | |
| lib/libc/string/strerror.c | ||
| 132 | This assumes that this function will be used commonly, which seems reasonable. | |
| 138–139 | A good encouragement for architectures to implement proper TLS :) However, do we want to leave this error completely undocumented? | |
| lib/libc/string/strerror.c | ||
|---|---|---|
| 138–139 | I think arch(7) should list arches which do not implement static thread-local storage, then we can reference ENOTSUP from there. But from what I see, there is no arches left that define NO_TLS. Still I think that maintaining NO_TLS in some form is advantageous because it easier port to the new architectires. We got 2 or 3 in recent times (depends on how to calculate, arm64, riscv, powerc elfv2). | |

| 130 ↗ | (On Diff #80745) | 🤷🏻♀️ i dunno what to tell you 🤷🏻♀️ after manually patching my /usr/include/string.h with https://lists.freebsd.org/pipermail/svn-src-head/2020-December/142563.html it started working i don't know if poudriere does anything funky here, but this is my observation. either way i now have a fresh build @ https://alpha.pkgbase.live/FreeBSD:13:amd64/ |
