hid_report_len(9)

💅 hid_report_len(9) 💅

okay so this page is from the Kernel API Manual, and it's about hid_report_len — the function that calculates the report length. Bestie, it's giving tiny-utility-icon energy, and we're gonna get through it together 🫶

✨ NAME ✨

hid_report_len — calculate the report length 💖

🌈 SYNOPSIS 🌈

u32 hid_report_len (struct hid_report *report );

🎀 ARGUMENTS 🎀

• report — the report whose length we want to know. That's it, that's the whole argument. Iconic minimalism 💅

🦋 DESCRIPTION 🦋

So the length counts the report ID byte, but only if the ID is nonzero and therefore is included in the report. Reports whose ID is zero never include an ID byte. No cap. That's the whole vibe check: nonzero ID = the ID byte gets counted; zero ID = no ID byte, ever 💀✨
