fmt_long(3)

💖 fmt_long(3) — Library Functions Manual 💖

okay so bestie, welcome to the fmt_long(3) page. it's giving very specific, very useful, and honestly kind of iconic. 💅

🎀 NAME 🎀

• fmt_long — write an ASCII representation of a long integer. that's the name, that's the vibe, periodt. 💖

✨ SYNTAX ✨

#include <libowfat/fmt.h>

size_t fmt_long(char *dest,long source);

🦋 DESCRIPTION 🦋

fmt_long writes an ASCII representation of source to dest — the characters are '-' and '0' through '9', base 10 — and it returns the number of bytes written. no cap. ✨

fmt_long does not append \0. no sneaky null terminator, bestie. 😭

If dest equals FMT_LEN (i.e. is zero), fmt_long returns the number of bytes it would have written. so you can vibe-check the length first. 💖

For convenience, fmt.h defines the integer FMT_LONG to be big enough to contain every possible fmt_long output plus \0. iconic. 👑
