kobject_uevent_env(9)

💖 kobject_uevent_env(9) 💖

okay bestie, welcome to the Kernel API Manual — this one's a lil function from the kernel's /lib era and she is very important, so grab your iced coffee and let's go 🧚✨

✨ NAME ✨

kobject_uevent_env — send an uevent with environmental data 🎀

🌸 SYNOPSIS 🌸

int kobject_uevent_env (struct kobject *kobj , enum kobject_action
action , char *envp_ext[] );

🦋 ARGUMENTS 🦋

• kobj — the struct kobject that the action is happening to 👑 this is the main character of the call, lowkey
• action — the action that is happening, like what this whole vibe is about 💅
• envp_ext — pointer to environmental data 🌈 yes bestie, you get to pass extra data in, it's giving "bring your own context"

💜 DESCRIPTION 💜

so the way this works: it returns 0 if kobject_uevent_env is completed with success 🎉 — or the corresponding error when it fails 😭. that's it, that's the whole summary, fr fr. success = 0, failure = the matching error code. no cap.

ngl this is the entire documented behaviour in the original page, so we are NOT inventing extra lore here. periodt 💀

⭐ SEE ALSO ⭐

• Kernel file ./lib/kobject_uevent.c 📁 (yes, the source file itself is listed as a SEE ALSO, iconic)
• kobject_synth_uevent(9)
• kobject_uevent(9)
• add_uevent_var(9)

and that's the page, bestie! 🫶 this one shipped from ./lib back in October 2026, so if you're reading it later just know she's been out here slaying since then 🌸💖 bye pookie, go send some uevents 💅✨
