scan_xlong(3)

💖 scan_xlong — the manual, but make it cute 💖

okay bestie, welcome to the Library Functions Manual 🎀 this is the scan_xlong(3) page and honestly? it's a little icon. let's get into it.

✨ NAME ✨

scan_xlong — parses an unsigned long integer in hexadecimal ASCII representation 🦋

like. it reads hex. it gives you a number. she's simple, she's effective, she ate 💅

🌸 SYNTAX 🌸

#include <libowfat/scan.h>

size_t scan_xlong(const char *src,unsigned long *dest);

copy it exactly, bestie, don't freestyle the includes 🙈

👑 DESCRIPTION 👑

okay so here's the tea, fr fr:

scan_xlong parses an unsigned long integer in hexadecimal ASCII representation from src and writes the result into dest. then — and this is the part people always forget — it returns the number of bytes read from src. so like, it's not just vibes, it tells you exactly how far it got. 🫶

scan_xlong understands both upper and lower case letters ✨ like a through f AND A through F, she's bilingual, she's inclusive, we love that for her 🌈

and this next one is important, so listen up: scan_xlong does not expect or understand a "0x" prefix. do not hand her a "0x". she will not know what to do with it. no cap 💀

so yeah, that's the whole page. short, sweet, main character energy, no notes. this was the Library Functions Manual version of scan_xlong(3), and that's the last line, periodt 💅✨💖
