Consistently present absent stdio handles on Windows as NULL handles. This addresses #90964 by making the std API consistent about presenting absent stdio handles on Windows as NULL handles. Stdio handles may be absent due to `#![windows_subsystem = "windows"]`, due to the console being detached, or due to a child process having been launched from a parent where stdio handles are absent. Specifically, this fixes the case of child processes of parents with absent stdio, which previously ended up with `stdin().as_raw_handle()` returning `INVALID_HANDLE_VALUE`, which was surprising, and which overlapped with an unrelated valid handle value. With this patch, `stdin().as_raw_handle()` now returns null in these situation, which is consistent with what it does in the parent process. And, document this in the "Windows Portability Considerations" sections of the relevant documentation. |
