div_t(3type)

✨ div_t, ldiv_t, lldiv_t, imaxdiv_t ✨ (the div_t family, bestie 💖)

okay so picture this: you're doing integer division and you want the leftover bits too, and instead of juggling two variables like a peasant, C hands you a whole lil struct for it. that's this page. it's a 3type page from the Linux man-pages, so it's all about types, not functions. sit down, grab a strawberry 🍓, let's go.

🌸 NAME 🌸

div_t, ldiv_t, lldiv_t, imaxdiv_t — the quotient and the remainder of an integer division, packaged together like a little duo. it's giving "two besties, one struct" 💅

🫶 LIBRARY 🫶

Standard C library (libc) — nothing exotic, she's in the standard library, she's been there the whole time, we stan.

✨ SYNOPSIS ✨

first up, from <stdlib.h>:

#include <stdlib.h>

typedef struct {
    int quot; /* Quotient */
    int rem;  /* Remainder */
} div_t;

typedef struct {
    long quot; /* Quotient */
    long rem;  /* Remainder */
} ldiv_t;

typedef struct {
    long long quot; /* Quotient */
    long long rem;  /* Remainder */
} lldiv_t;

and then this one lives somewhere else entirely, from <inttypes.h>:

#include <inttypes.h>

typedef struct {
    intmax_t quot; /* Quotient */
    intmax_t rem;  /* Remainder */
} imaxdiv_t;

no cap, that's the whole synopsis. four little structs. each one has a quot field (the quotient, obviously, main character behavior) and a rem field (the remainder, the supporting actor who is also iconic). 🎀

💜 DESCRIPTION 💜

[[l]l]div_t is the type of the value returned by the [[l]l]div(3) function. like, all of those bracketed versions — div_t, ldiv_t, lldiv_t — they're that family. the brackets are just doing their little "pick your size" thing. 😌

imaxdiv_t is the type of the value returned by the imaxdiv(3) function. different header, different function, same exact energy. 🦋

and that's it! that's the whole description. short and snappy, we love a concise queen.

📜 STANDARDS 📜

C11, POSIX.1-2024. periodt. ✅

⭐ HISTORY ⭐

we're going era by era, so buckle up:

• div_t
• ldiv_t — SUSv1, C99, POSIX.1-2001.
• lldiv_t
• imaxdiv_t — C99, POSIX.1-2001.

so div_t and ldiv_t go way back, SUSv1 old, ancient, legendary ancestors 👑 — while lldiv_t and imaxdiv_t showed up later, with C99 and POSIX.1-2001. everyone arrived eventually, it's fine, fashionably late is still a serve. 💀✨

okay and for the sign-off: this gorgeous lil page is from Linux man-pages 6.20, dated 2026-02-08. go forth and divide integers responsibly, bestie 🫶💖🌸
