💅 qlibs:(fd) — the fd page, but make it bestie-coded 💅

okay so this is the qlibs:(fd) manual, page 3 energy, and we’re talking about file-descriptor glow-ups: duplicating, moving, and closing. no cap, every detail is staying. 🫶

🌸 NAME 🌸

fd — duplicate, move or close a file descriptor.

✨ SYNTAX ✨

#include "fd.h"

int fd_copy(int to,int from);
int fd_move(int to,int from);
int fd_coe(int fd);

🦋 DESCRIPTION 🦋

• fd_copy — copies descriptor from to descriptor to. If to was already open, fd_copy closes it. fd_copy always leaves from intact; if to and from are the same number, fd_copy does nothing.

🚨 caveat, bestie: fd_copy does not guarantee that to will remain open, if it was open, in case of error.

• fd_move — moves descriptor from to descriptor to. If to was already open, fd_move closes it. If the move is successful, fd_move closes from. Exception: if to and from are the same number, fd_move does nothing.
• fd_coe — closes fd.

💀 RETURN CODES 💀

fd_copy, fd_move, and fd_coe return 0 on success, and -1 on error. that’s it, that’s the whole vibe check. ✨
