binder_inc_ref_olocked(9)

okay bestie, welcome to binder_inc_ref_olocked(9) from the Kernel API Manual — this is the page about incrementing the ref for given handle 💅✨

💖 NAME 💖

binder_inc_ref_olocked — increment the ref for given handle. That's the assignment, and it ate. 💖

✨ SYNOPSIS ✨

int binder_inc_ref_olocked (struct binder_ref *ref , int strong , struct list_head *target_list );

🎀 ARGUMENTS 🎀

okay so here's the cast, bestie:

• ref — the ref that's getting incremented. Main character of this call, honestly. 🫶
• strong — if this is true, you're doing a strong increment; otherwise it's a weak one. Binary queen. 💅
• target_list — the list you queue node work on. Drop the node work there. 🎀

🦋 DESCRIPTION 🦋

Increment the ref. That's the move. But the lock vibe check is real: ref->proc->outer_lock must be held on entry.

⚠️ no cap: ref->proc->outer_lock must be held on entry. Like, held before you call this, bestie. Don't skip the lock. 😭

🌸 RETURN 🌸

It returns 0 if successful, else errno. So 0 is the slay outcome; anything else is the errno situation. ✨
