uint16_unpack_big(3)

💖 uint16_unpack_big — bestie edition 💖

okay so real quick, the manual name is Library Functions Manual and the page is uint16_unpack_big(3), and we're about to make big-endian bytes behave. no cap.

✨ NAME ✨

uint16_unpack_big — read an unsigned big-endian 16-bit integer 🌸

✨ SYNTAX ✨

like, this is literally what you type, copy it exactly bestie:

#include <libowfat/uint16.h>

uint16 u;

void uint16_unpack_big(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. that's it, that's the type. 🎀

and uint16_unpack_big? okay so the way that it works is: it portably reads a uint16 as stored on a big-endian architecture (i.e. in network byte order) from s, and writes it into u in the native byte order. 🦋

the whole vibe is "the bytes came in big-endian, but your machine might not be, and we are not about to let that be your problem." it handles the portability for you. iconic. 👑

heads up: s is a const char s[2] — it points at exactly 2 bytes, and u is a uint16 *, so the result lands wherever that pointer says. 💅

✨ SEE ALSO ✨

• uint16_pack_big(3) — the other half of this situationship 🫶
• uint16_unpack(3) — the sibling that's not locked to big-endian ⭐

okay that's the whole page bestie, you ate, go unpack some bytes 💜

this was the uint16_unpack_big(3) page out of the Library Functions Manual (that's the source/version vibe, no date on this one, we keep it mysterious 🙈) — mwah, slay, periodt 💖✨
