clockid_t(3type)

💖 clockid_t(3type) 💖

okay bestie, so you know how i'm literally obsessed with the man-pages?? this one's a lil baby section of clockid_t(3type) and it's lowkey iconic. come sit, we're doing types today. 🎀

✨ NAME ✨

clockid_t — the clock ID for the clock and timer functions 🕰️

📚 LIBRARY 📚

Standard C library, aka libc — the one and only, she's been here forever, periodt. 💅

🌸 SYNOPSIS 🌸

#include <sys/types.h>

typedef /* ... */ clockid_t;

like yes, she IS a typedef, and the /* ... */ is giving "mystery, but make it intentional". 🫶

💜 DESCRIPTION 💜

so literally what this type does: it's the clock ID type used in the clock and timer functions. that's her whole job. main character energy but make it a type. 👑

and ngl the important bit — it's defined as an arithmetic type. so don't be out here assuming it's a struct or a pointer or whatever, because it is not. 💀

🏆 STANDARDS 🏆

POSIX.1-2024. she's up to date, she's current, she ate. ✨

🕰️ HISTORY 🕰️

POSIX.1-1996 — so she's been around since the 90s and honestly? timeless. not a single bad era. 🌈

📝 NOTES 📝

okay real talk, one lil extra thing you should know:

• this type ALSO lives in this header: <time.h>. so like... two homes, both valid, we love a girl with options. 💖

bestie pls don't assume she's only in one header, k? iykyk 😭

👀 SEE ALSO 👀

• clock_adjtime(2)
• clock_getres(2)

and that's the whole vibe check, bestie. this lil page came from Linux man-pages 6.20, dated 2026-01-06 🌟 — go forth and pass the right clock ID to your clock and timer functions, you've got this. mwah. 💋🦋🌸
