#2204 : use std handles if associated with streams

Does -2 have a constant name somewhere defined?

[mrjbq7]

Should we open nul only once using r+ and share the handle or is that not necessary? since they can be closed independently by factor?

I think it's indeed better to have 3 independent handles

I can introduce a constant, but I didn't see anything mentioned in the documentation

There's no named constant for this. i asked chatgpt so it's true.

we could do this if we wanted though:

#define INVALID_HANDLE_FD -2
#define VALID_HANDLE(handle, mode) (_fileno(handle) == INVALID_HANDLE_FD ? fopen("nul", mode) : handle)
