fmt_copybytes(3)

💖 fmt_copybytes — a manual page, but make it cute 💖

okay so bestie, welcome to fmt_copybytes(3) from the Library Functions Manual 🫶 this one is short, sweet, and honestly kind of a slay. let's get into it.

✨ NAME ✨

fmt_copybytes — write binary data 💾✨

like. literally just copy some bytes. that's the whole job. and she does it flawlessly.

🌸 SYNTAX 🌸

#include <libowfat/fmt.h>

size_t fmt_copybytes(char *dest,const char *source, size_t limit);

look at that signature. clean. iconic. no notes. 👑

🦋 DESCRIPTION 🦋

so here's the tea, bestie ☕ — fmt_copybytes copies limit bytes from source to dest and returns limit. that's it. that's the function. she copies, she returns the number, she leaves. main character behaviour, honestly 💅

ngl this one is a convenience wrapper interface around memcpy / byte_copy, and the whole reason she exists is to make byte-copying work like all the other fmt functions do 🌈 so if you're already vibing in fmt-land and you need a raw byte copy that matches the rest of the crew, she's your girl. no cap.

fr fr: she returns limit, not something else. don't overthink it. the way that limit goes in and limit comes back out is lowkey poetic 🎀
