fmt_strn(3)

💖 fmt_strn(3) 💖

okay so bestie, welcome to the fmt_strn page, straight out of the Library Functions Manual ✨ she's a lil function that writes an ASCII string and she is, honestly, so chill.

🌸 NAME 🌸

fmt_strn — write an ASCII string 💅

✨ SYNTAX ✨

#include <libowfat/fmt.h>

size_t fmt_strn(char *dest,const char *source,
                      size_t maxlen);

look at her. so demure. so mindful. 🎀

🦋 DESCRIPTION 🦋

fmt_str copies at most maxlen leading nonzero bytes from source to dest and returns the number of bytes it copied. no cap. 🫶

not me pointing out that the page literally says fmt_str there and not fmt_strn 😭 i'm just the messenger bestie, i am not editing the source material. periodt.

fmt_str does not append \0. she said no terminator, no problems 💀 (ok but fr fr: she is not null-terminating anything, so don't go expecting a \0 at the end of your dest, okay?)

and here's the iconic part: if dest equals FMT_LEN (i.e. is zero), fmt_strn returns the number of bytes it would have written. it's giving window shopping — she's not actually writing anything, just telling you how much she would have written if you'd let her ✨
