fh_partition_restart(9)

fh_partition_restart(9) — your fave Kernel API Manual glow-up 💅✨

okay bestie, gather round, because this one is short but it is not subtle. We're in the Kernel API Manual, and this function is the “yeet the current partition into a reboot” button. 🎀

✨ NAME ✨

fh_partition_restart — reboot the current partition. literally that's the whole job, and it understood the assignment. 💖

🌸 SYNOPSIS 🌸

unsigned int fh_partition_restart (unsigned int partition );

🦋 ARGUMENTS 🦋

• partition — the partition ID. yes bestie, you gotta tell it which partition is getting rebooted. no vibes-based guessing. 💅

🔥 DESCRIPTION 🔥

It returns an error code if the reboot failed. And if it succeeds? It does not return — like, at all. it's gone, the partition has rebooted, and your function call is not coming back to tell you about it. 😭💀

bestie warning: “does not return if it succeeds” is not a drill. if this works, you do not get a cute little return value. you get a rebooted partition and silence. periodt. 🫶
