input_alloc_absinfo(9)

✨ NAME ✨

input_alloc_absinfo — allocates array of input_absinfo structs. This is the input_alloc_absinfo(9) page from the Kernel API Manual, and honestly it’s giving “small but crucial” 💅.

🌸 SYNOPSIS 🌸

void input_alloc_absinfo (struct input_dev *dev );

🎀 ARGUMENTS 🎀

• dev — the input device emitting absolute events. That’s the main character here 🫶.

🦋 DESCRIPTION 🦋

Okay so here’s the vibe check: if the absinfo struct the caller asked for is already allocated, this function will not do anything. Like, it sees the allocation already exists and just minds its own business 💀✨. No extra allocation, no side quest, no nothing. Periodt.
