witch_t *naviwe have pid_t and gid_t and uid_t but no fd_t
they're all ints why did fds get left out of the typedef club qwq

humm@humm it's part of annex K iirc and things just don't implement annex K at all
but yeah returning errno_t instead of 'int' would be a lot better

Laurent Bercot@navi @humm Why do yall think that the multiplication of integer types is a good thing?
It's boilerplate, it makes the code less clear, it bloats header files, and if I need to serialize it I need to add a sysdep test to know what size it is. And the benefits of having specific integer types are dubious at best, I've never seen a strong argument for them.
What makes you want fd_t and errno_t over int or, if anything, int32_t?
@ska @humm
because it isn't any random int, it's a file descriptor, or an error, it has semantic meaning beyond the fact that it's represented by a number
you wouldn't do arithmetic with any of them, you wouldn't type a random literal to a function that takes a fd -- the fd represents and object, not a number by itself

@navi @humm Okay that makes sense, but it's in the nature of C to use int as a generic handle, and because it's an int doesn't mean you're going to do arithmetic with it. The integers I do arithmetic with are almost exclusively uint32_t, because 1. I want to know what their range is, and 2. in system programming, I never need negative numbers.
int is terrible for arithmetic for these reasons, and on the other hand it's a pretty good type for a handle: wide enough for all your needs and you don't really care if it's 32 or 64 bits, can use negative numbers for e.g. error values, has an ordering so you can use it as a key for sorting and logarithmic searches, etc.
This is a volcanic take, but I'd be okay with removing arithmetic operations from int (as long as you keep comparisons) and making it a handle-only type 😝
