hid_map_usage_clear(9)

okay bestie, welcome to the hid_map_usage_clear(9) page from the Kernel API Manual ✨. No cap, we’re about to map some usage input bits and clear the input bit 💅.

🌸 NAME 🌸

hid_map_usage_clear — map usage input bits and clear the input bit. That’s the whole name, and honestly it ate 🫶.

✨ SYNOPSIS ✨

void hid_map_usage_clear (struct hid_input *hidinput , struct hid_usage
       *usage , unsigned long **bit , int *max , __u8 type , __u16 c );

🎀 ARGUMENTS 🎀

• hidinput — the hidinput we’re interested in 👀
• usage — the usage to fill in
• bit — pointer to input->{}bit (out parameter)
• max — maximal valid usage->code to consider later (out parameter)
• type — input event type (EV_KEY, EV_REL, ...)
• c — code which corresponds to this usage and type

🦋 DESCRIPTION 🦋

Okay so it’s literally the same as hid_map_usage, except the c bit is also cleared in supported bits (bit). That’s the whole plot twist 🎬. Periodt 💖.
