buffer_feed(3)

✨ buffer_feed(3) ✨

okay so bestie, welcome to the <strong>Library Functions Manual</strong> entry for buffer_feed</strong> — she's a low-level girly and she's literally the backbone of buffer_get. 💅

---

🌸 NAME 🌸

buffer_feed — the low-level component of buffer_get, aka the behind-the-scenes main character 🎀

---

🦋 SYNTAX 🦋

#include <libowfat/buffer.h>

ssize_t buffer_feed(buffer* b);

that's it, that's the whole vibe check. one include, one function, one pointer. slay. ✨

💖 DESCRIPTION 💖

So here's the tea ☕ — the way buffer_feed behaves depends entirely on whether the string is <em>nonempty</em> or <em>empty</em>, and ngl it's giving "two moods":

• If the string is nonempty, buffer_feed returns the length of the string. That's it. No reads, no drama, just the number. 👑
• If the string is empty, buffer_feed uses the read operation to feed data into the string 🫶 — and then it returns the new length of the string.

And when it does that read-y thing, there are two special returns you gotta know about, fr fr:

• 0 — that's end of input, no more data coming, the era is over 😭
• -1 — that's an error. not cute. handle her. 💀
