touchscreen_set_mt_pos(9)

💅 touchscreen_set_mt_pos — like, the Kernel API Manual page, bestie

okay so picture this: you're deep in the kernel, you've got raw touch coordinates, and you just want them to make sense. that's this function. it's giving "glow-up for numbers" ✨

---

🌸 NAME 🌸

touchscreen_set_mt_pos — sets the coordinates in an input_mt_pos. that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

void touchscreen_set_mt_pos (struct input_mt_pos *pos , const struct
       touchscreen_properties *prop , unsigned int x , unsigned int y );

no cap, that's the exact signature. don't @ me about the line break, it came like that 💀

---

👑 ARGUMENTS 👑

• pos — the input_mt_pos you're setting coordinates of. like, this is the little container getting the makeover 🫶
• prop — pointer to a struct touchscreen_properties. this is where the axis-inversion and swapping instructions live, iykyk
• x — the X coordinate to store in pos
• y — the Y coordinate to store in pos

---

🔥 DESCRIPTION 🔥

here's the tea ☕: you hand it an x and a y, and it adjusts them — applying whatever axis inversion and swapping was requested in the touchscreen_properties you passed in — and then it stores the result in a struct input_mt_pos.

literally the whole plot. transform in, transform out, main character energy the entire time 💅✨

🌈 SEE ALSO 🌈

• the kernel file ./drivers/input/touchscreen.c — go read it, it's iconic
• touchscreen_parse_properties(9) — the one that figures out all those properties in the first place
• touchscreen_report_pos(9) — the sibling function, also ate 🍓

and that's the page!! fr fr you're basically a touchscreen expert now 🧚
