fmt_strm(3)

✨ NAME ✨

hey bestie, welcome to the fmt_strm(3) page from the Library Functions Manual 🫶 this one is lowkey iconic: she writes multiple ASCII strings, no cap.

• fmt_strm — write multiple ASCII strings 💖

---

🦋 SYNTAX 🦋

#include <libowfat/fmt.h>

size_t fmt_strm(char *dest,const char *source, ...);

---

🌸 DESCRIPTION 🌸

okay so picture this: fmt_strm copies all leading nonzero bytes from source and the following function arguments into dest 💅 then she returns the number of bytes she copied. periodt.

she does not append \0, bestie. not even a little. 🙈

now for the main-character plot twist: if dest equals FMT_LEN (i.e. is zero), then fmt_str returns the number of bytes it would have written — that's the number of leading nonzero bytes of source and the following function arguments. ✨

ngl the original text says fmt_str right there, not fmt_strm — so we're keeping it exactly as written, fr fr. no edits, no erasure, just facts. 💯

and that's the vibe check: this page comes from the Library Functions Manual, and the footer just signs off as fmt_strm(3) — no version or date on this one, so that's the cute sign-off, bestie 💖✨
