buffer_putulong(3)

💖 buffer_putulong — the manual page, but make it cute 💖

okay so bestie, this one is a lil function from the Library Functions Manual, and it's called buffer_putulong(3). yes it's a mouthful, yes it's iconic, let's get into it 🫶

---

✨ NAME ✨

buffer_putulong — write a decimal ASCII representation of an unsigned long integer to buffer

like. it takes your number, turns it into readable decimal digits, and yeets them into a buffer. that's the whole job. she's a specialist 💅

---

🌸 SYNTAX 🌸

#include <libowfat/buffer.h>

int buffer_putulong(buffer* b,unsigned long x);

so you gotta #include that header, no skipping it, the compiler WILL notice and it WILL be embarrassing 😭

then you call her with a buffer* (that's b, the destination) and an unsigned long (that's x, the number getting the glow-up into text).

---

🦋 DESCRIPTION 🦋

buffer_putulong is similar to passing the result of fmt_ulong to buffer_put.

that's it. that's the description. she said "why do it in two steps when one step exists" and honestly? main character energy 👑

so instead of formatting your number with fmt_ulong and then shoving the result into buffer_put, you just... call this one. same vibe, fewer keystrokes. iykyk ✨

🎀 RETURN VALUE 🎀

• 0 — everything is fine, we ate, no notes 💖
• -1 — error, and it's setting errno so you can go find out what went wrong 🔍

bestie check the return value ok. -1 means something went sideways and errno is holding the receipts 🙈

go read the whole lil family, they're all connected, it's giving found family 🥹

and that's the whole page!! this was buffer_putulong(3) from the Library Functions Manual — no fancy version stamp or date on this one, she's just out here being timeless and useful 🕰️✨

mwah, go write some bytes, bestie 💅💖🌸
