uint64_pack_big(3)

💖 uint64_pack_big — bestie's guide to the manual 💖

okay so this is the uint64_pack_big(3) page, living in the Library Functions Manual, section 3, and it's literally just one little function that does one little thing and does it so well. no cap.

✨ NAME ✨

uint64_pack_big — write an unsigned big-endian 64-bit integer 🫶

🌸 SYNTAX 🌸

bestie, you gotta pull in the header first, always:

#include <libowfat/uint64.h>

then you got your variable, iconic, mysterious, just vibing:

uint64 u;

and then the main character herself:

void uint64_pack_big(char s[4],uint64 u);

🦋 DESCRIPTION 🦋

so uint64 is a 64-bit unsigned integer type. that's it, that's the whole personality. 64 bits, unsigned, no negativity allowed 💅

and uint64_pack_big? she portably writes a uint64 u into s in big-endian byte order — which is the same thing as network byte order, iykyk. so when you send your bytes out into the world, they're in the order the internet expects, on every machine, every time. portable. consistent. a queen. 👑

note the vibes: it writes to s, it doesn't return anything — the return type is void. it's giving "I don't need credit, I just do the work." main character energy fr fr.

• uint64_pack(3) — same energy, different byte-order situation 💜

and that's the whole page, bestie! it's short, it's sweet, it's efficient. this manual page came from the Library Functions Manual as page uint64_pack_big(3) — no fancy version stamp, no date, just the name in the corner being cute. mwah. 💋 go forth and pack those bytes big-endian. periodt. ✨🌸💖
