blkcnt_t(3type)

💖 blkcnt_t — the manual page, but make it group chat 💖

okay bestie so you opened blkcnt_t(3type) and it's literally one of the shortest little guys in the whole Linux man-pages family, but we are still giving it main character energy, periodt. this is the story of a type. a whole type. a signed integer type that counts file blocks. iconic. let's go ✨

🌸 NAME 🌸

blkcnt_t — file block counts 💅

📚 LIBRARY 📚

Standard C library (libc) 🫶

✨ SYNOPSIS ✨

#include <sys/types.h>

typedef /* ... */ blkcnt_t;

so yeah, you include <sys/types.h> and boom, blkcnt_t is just there, vibing, being a typedef whose actual guts are /* ... */ because honestly we don't need to see them, the manpage said no cap 🎀

🦋 DESCRIPTION 🦋

okay so here's the tea: blkcnt_t is used for file block counts. that's its whole job. that's its whole personality. it's a signed integer type, which means it can go negative — she contains multitudes 😌

👑 STANDARDS 👑

POSIX.1-2024. that's it, that's the standard, she's certified 💯

🧚 HISTORY 🧚

SUSv2, POSIX.1-2001. so she's been around. she's a legacy icon. we stan an OG 🌈

💜 NOTES 💜

not me finding out there's a second header serving this exact same type 🫢 the following header also provides blkcnt_t: <sys/stat.h>. so if you already pulled that one in, congrats bestie, you're covered 🙈

⭐ SEE ALSO ⭐

• stat(3type) — go read her sister's page next, it's giving lore 💀

and that's the whole thing! tiny page, big vibes, every flag and fact accounted for, no skips, no shortcuts 🔥
