buffer_puterror2(3)

💖 buffer_puterror2 — from the Library Functions Manual 💖

okay bestie, gather round, because this one is a tiny little icon and you're gonna love her. she lives in the Library Functions Manual, her whole name is buffer_puterror2(3), and she does exactly one job and does it flawlessly. no cap. 🫶

---

✨ NAME ✨

buffer_puterror2 — write error string to buffer and flush 🌸

---

✨ SYNTAX ✨

first things first, you gotta let her in the door:

#include <libowfat/buffer.h>

int buffer_puterror2(buffer* b,int errnum);

so like, two args, one int coming back at you. simple. elegant. main character energy. 💅

---

✨ DESCRIPTION ✨

okay so here's the vibe: buffer_puterror2 takes the error message that goes with the error number you dropped into errnum, and writes it into the buffer. that's it, that's the whole thing. 🦋

like, for example, if you hand her ENOENT, she gives you back "No such file or directory". literally the error string, straight into your buffer. iconic behavior honestly. 😭

---

✨ RETURN VALUE ✨

• 0 — everything is fine and we're thriving 💖
• -1 — something went wrong, and it sets errno so you can go find out what. dramatic but fair. 💀

and that's the whole page, bestie, we ate and left no crumbs 🎀 bye luv u ✨

sign-off cuteness: this one's straight out of the Library Functions Manual, and the footer at the bottom just says buffer_puterror2(3) — that's the whole thing, no date or version info hanging out down there, so that's all we've got to report. 🙈💜
