SCANF_L(3)

🌸 NAME 🌸

Okay bestie, meet the _l scan squad: scanf_l, fscanf_l, sscanf_l, vfscanf_l, vscanf_l, and vsscanf_l — it’s giving input format conversion 💅✨. This is the SCANF_L(3) page, hanging out in the Library Functions Manual, and yes, it’s literally the locale-flavored scan family 🫶.

🦋 LIBRARY 🦋

Library check: Standard C Library (libc, -lc) — that’s the whole vibe 🧚💖.

---

✨ SYNOPSIS ✨

Copy-paste era, but keep it exact bestie — every line and every restrict stays right where it is:

#include <stdio.h>
#include <xlocale.h>

int
scanf_l(locale_t loc, const char * restrict format, ...);

int
fscanf_l(FILE * restrict stream, locale_t loc,
    const char * restrict format, ...);

int
sscanf_l(const char * restrict str, locale_t loc,
    const char * restrict format, ...);

int
vfscanf_l(FILE * restrict stream, locale_t loc,
    const char * restrict format, va_list ap);

int
vscanf_l(locale_t loc, const char * restrict format, va_list ap);

int
vsscanf_l(const char * restrict str, locale_t loc,
    const char * restrict format, va_list ap);

---

💅 DESCRIPTION 💅

So the above functions scan input according to a specified format, but they do it in the locale loc 👑. They behave the same way as the versions without the _l suffix, except they use the specific locale instead of the global or per-thread locale 🌈. For the full tea, see the specific manual pages — iykyk 🍓.

🔥 SEE ALSO 🔥

• scanf(3)
• xlocale(3)

Go read those if you want the deeper lore 💜.

⭐ STANDARDS ⭐

Heads up: these functions do not conform to any specific standard, so they should be considered as non-portable local extensions 💀. Slay locally, but don’t expect them to travel everywhere, fr fr.

---

🎀 HISTORY 🎀

These functions first appeared in Darwin and were first implemented in FreeBSD 9.1 🦋✨. Little icon behavior.

Cute sign-off time: this page’s footer tea is Debian and the date April 8, 2012 💖🎀. That’s the source/version-and-date moment, wrapped up with a bow 🫶🌸.
