[libc-commits] [libc] [libc][docs] Add pwd.h POSIX header documentation (PR #186292)

[via libc-commits]

https://github.com/kovan created https://github.com/llvm/llvm-project/pull/186292

Add YAML metadata for `pwd.h` listing all POSIX-mandated functions
(`endpwent`, `getpwent`, `getpwnam`, `getpwnam_r`, `getpwuid`,
`getpwuid_r`, `setpwent`). This header defines no macros per POSIX.

Add `pwd` to `index.rst` and `CMakeLists.txt` `docgen_list`.

Verified with `python3 docgen.py pwd.h` — generates valid RST with correct POSIX links.

Partial fix for #122006
