I already have the C equivalent of $sock ...

What do you mean by that? What is it that you have and where did it come from?

My probably incomplete understanding of this is that unlike *nix, where sockets masquarade as files (File*), WS2 sockets are natively completely different beasts and cannot be used directly with the vast majority of APIs that expect a native file handle, and certainly not be used with CRT calls that expect a FILE*.

Perl works around this difference in platform semantics by (in the terms of the comments) "faking it". See the routine _alloc_osfhnd() in win32.c(~2200) for some info. Basically, they open a native handle to NUL, and build a fake CRT FILE* around it and use that to allow *nix-style semantics to operate on WS2 handles.

Depending what you have and where you got it from, you might have to emulate that in order to achieve your goal.

In the absence of evidence, opinion is indistinguishable from prejudice.
