FDUP(3)

✨ FDUP(3) — NAME ✨

fdup() — returns new file identical to the given file. that’s the whole vibe, bestie. 💅

🌸 SYNOPSIS 🌸

okay so here’s the exact shape of it:

FILE fdup(f)
FILE *f;

🦋 DESCRIPTION 🦋

okay so fdup() creates a new file stream that accesses the same file as f. the new file has the same read/write/buffered attributes as the old file — literally matching energy, no cap. and yes, fdup() can be used to simultaneously read from two different positions in a file. iconic behavior. ✨

🎀 RETURNS 🎀

• if it’s successful, it returns the duplicate file. slay. 💖
• if it could not create the new stream, it returns NULL. 😭

💜 NOTES 💜

⚠️ bestie, use this call carefully on buffered files that are open for writing. changes made on one stream might be superseded by changes made on the other. so like… don’t let the streams fight, okay? 🙈
