binder_inc_ref_for_node(9)

💖 NAME 💖

Hey bestie! Welcome to binder_inc_ref_for_node(9) from the Kernel API Manual — this one is lowkey iconic. It’s here to increment the ref for a given proc/node. 🫶

binder_inc_ref_for_node — increment the ref for given proc/node.

✨ SYNOPSIS ✨

int binder_inc_ref_for_node (struct binder_proc *proc , struct
       binder_node *node , bool strong , struct list_head *target_list ,
       struct binder_ref_data *rdata );

🎀 ARGUMENTS 🎀

• proc — the proc containing the ref. 💖
• node — target node. 🎯
• strong — true=strong reference, false=weak reference. 💪
• target_list — worklist to use if node is incremented. 🗂️
• rdata — the id/refcount data for the ref. 🍓

🦋 DESCRIPTION 🦋

Okay so picture this: you hand over a proc and a node, and the mission is to increment the ref. If that ref doesn’t already exist, this function creates it — no cap, it’s giving “make it happen” energy. ✨

🔥 RETURN 🔥

Returns 0 if successful, else errno. That’s the whole return story, bestie. 💅
