💖 clock_t(3type) 💖

okay bestie, welcome to the clock_t(3type) page — yes that's the manual name, 3type just means "this is a type, not a function," we love a categorized queen 💅

✨ NAME ✨

clock_t — system time 🕰️

📚 LIBRARY 📚

Standard C library (libc) 🫶

🌸 SYNOPSIS 🌸

#include <time.h>

typedef /* ... */ clock_t;

🦋 DESCRIPTION 🦋

so like, this type is what you use for system time — measured in clock ticks, or in units of CLOCKS_PER_SEC, which is defined in <time.h> ✨

and per POSIX? it's either an integer type or a real-floating type. that's it, that's the whole vibe check. no cap. 💫

👑 STANDARDS 👑

• C11
• POSIX.1-2024

she's official, she's certified, she's on the standards board 🎀

🧚 HISTORY 🧚

• C89
• POSIX.1-1988

an OG. been here since before most of us could walk, lowkey iconic 🌈

💜 NOTES 💜

plot twist bestie — it's not just <time.h> that's holding her. these headers also provide this type too:

• <sys/types.h>
• <sys/times.h>

so if you're importing from one of those and clock_t just shows up? that's why. iykyk 😌
