[libc][NFC] clean internal fd handling (#143991)

2025-06-13T17:31:47+00:00

The previous internal fcntl implementation modified errno directly, this
patch fixes that. This patch also moves open and close into OSUtil since
they are used in multiple places. There are more places that need
similar cleanup but only got comments in this patch to keep it
relatively reviewable.

[libc] Add the implementation of the fdopen function (#94186)

2024-06-14T23:17:44+00:00

Fixes #93711 .
This patch implements the ``fdopen`` function. Given that ``fdopen`` 
internally calls ``fcntl``, the implementation of ``fcntl`` has been
moved to the ``__support/OSUtil``, where it serves as an internal public
function.

[libc] Implement fcntl() function (#89507)

Fixes #84968. 

Implements the `fcntl()` function defined in the `fcntl.h` header.
