msleep_interruptible(9)

💤 msleep_interruptible(9) — a Kernel API Manual moment, bestie ✨

🎀 NAME 🎀

msleep_interruptible — sleep waiting for signals. literally the “nap until someone signals me” icon 💅✨

🌸 SYNOPSIS 🌸

unsigned long msleep_interruptible (unsigned int msecs );

🦋 ARGUMENTS 🦋

• msecs — the requested sleep duration, in milliseconds. that’s your nap length, bestie ⏳💖

💖 DESCRIPTION 💖

For some basic information, see msleep — this page is lowkey telling you to check that one for the basics 🫶

The difference between msleep and msleep_interruptible is that the sleep could be interrupted by a signal delivery and then returns early. so yes, the nap can get cut short by a signal and it comes back early — not me waking up before my alarm 😭💀

so real talk: the sleep could be interrupted by signal delivery and return early. don’t act surprised when it does, bestie 🚨💅

🌈 RETURN 🌈

The remaining time of the sleep duration transformed to msecs — see schedule_timeout for details. leftover nap time, in milliseconds, handed right back to you 🫶⏰
