uint16_unpack(3)

💖 uint16_unpack — bestie edition 💖

okay so this is a page from the Library Functions Manual, and the function we're obsessing over today is uint16_unpack. grab a snack, we're decoding bytes 🍓

✨ NAME ✨

uint16_unpack — read an unsigned little-endian 16-bit integer 👑

no cap, that's the whole vibe: it reads a lil 16-bit unsigned int for you.

---

🌸 SYNTAX 🌸

first things first, you gotta invite the header to the party:

#include <libowfat/uint16.h>

then declare ur lil guy:

uint16 u;

and here's the main character herself, the function signature, copy it exactly bestie:

void uint16_unpack(const char s[2],uint16 *u);

🦋 DESCRIPTION 🦋

so uint16 is a 16-bit unsigned integer type. it's normally either unsigned int or unsigned long depending on what your machine woke up feeling like that day 💅

now the actual tea: uint16_unpack portably reads a uint16 — as stored on a little-endian architecture — from s, and writes it into u in the native byte order. so like, whatever endianness your machine speaks natively, that's what you get in u. iconic behaviour, honestly. it's giving translator 🫶

the way that this is portable is the whole point — you don't gotta worry about what endian your box is running, the function handles it. slay.

that's the whole page bestie, no notes 💀✨ this one's from the Library Functions Manual — that's the manual name right there in case u were wondering — and it's signed off by none other than uint16_unpack(3) herself. no version, no date, just vibes and a name. periodt 💅🌸🦋
