But reading/writing, closing these file descriptors is always the same.
For sockets you'd typically use `recv` and `send` instead or `read` and
`write` because the former give extra options and the latter don't work
on Windows. But yeah, on Linux `read` and `write` should work
universally among file descriptors.
I typically only use `send` and `recv` for for connectionless sockets.
For TCP sockets, it's generally `read` and `write` for me (and it works
fine).
Windows is a different story, they have different i/o routines for
system calls (yes, there's the shims for Posix file descriptors, but I
wouldn't use those anyway).
The larger point is that the reason `read`/`write` are separate from
descriptor creation is because they are universal, while creation is not.
