Path.sameOpenFile

bool sameOpenFile(int fd1, int fd2)

Returns true if two open files refer to the same underlying file object.

This is an equivalent of Python's os.path.sameopenfile.

Platform semantics:

POSIX: Compares st_dev and st_ino obtained via fstat(2) on both

file descriptors.

Windows: Best-effort fallback — compares FILE* pointers identity when

using the File overload. The fd-based overload returns false as a conservative answer. This limitation is documented; a future task may implement proper identity using Win32 APIs.

Parameters

`fd1`	First open file descriptor.
`fd2`	Second open file descriptor.

Returns

true if both refer to the same file object; false otherwise.

bool sameOpenFile(File f1, File f2)

Returns true if two std.stdio.File handles refer to the same file.
