ITIMERFIX(9)

💖 NAME 💖

okay so bestie, welcome to the itimerfix(9) kernel developer's manual page — yes, that's the manual name, we're folding it in right here. This one is all about itimerfix — check that a timeval value is valid, and correct 💅

✨ SYNOPSIS ✨

#include <sys/time.h>

int
itimerfix(struct timeval *tv);

🦋 DESCRIPTION 🦋

itimerfix is the little vibe check for your struct timeval *tv. It checks that the value in tv is valid — specifically, it wants 0 ≤ tv->tv_sec && 0 ≤ tv->tv_usec < 1000000 — and it also checks that the total time represented is at least one tick, or zero. no cap, that's the whole check 🫶

And if the total represented time is nonzero but smaller than a tick? Then it gets adjusted to exactly one tick. slay, corrected ✨

🎀 RETURN VALUES 🎀

• 0 — success, we love to see it 💖
• EINVAL — returned if tv is invalid 🙈
