SDL_HID_GET_SERIAL_NUMBER_STRING(3)

💖 SDL_hid_get_serial_number_string — from the SDL3 FUNCTIONS manual 💖

okay bestie, gather round, because we're about to read a whole device's serial number and it's honestly iconic 🎀

✨ NAME ✨

SDL_hid_get_serial_number_string — get the serial number string from a HID device, no cap 🦋

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_hidapi.h>

int SDL_hid_get_serial_number_string(SDL_hid_device *dev, wchar_t *string, size_t maxlen);

like yes that's the whole vibe, three little args and a dream 💅

---

✨ FUNCTION PARAMETERS ✨

• dev — a device handle returned from SDL_hid_open(). it's giving "i already know this device", so you gotta have opened it first, periodt 👑
• string — a wide string buffer to put the data into. this is where the serial number gets to live its main character era ✨
• maxlen — the length of the buffer in multiples of wchar_t. not bytes, bestie, wchar_t — read it twice, iykyk 🌸

---

✨ RETURN VALUE ✨

Returns 0 on success or a negative error code on failure 😭 and when it fails you should call SDL_GetError() for more information, because that's where the tea lives 🍓

---

✨ AVAILABILITY ✨

This function is available since SDL 3.2.0. so if you're on anything older, sorry babe, no serial number for you 💀

---

lowkey important: maxlen is in wchar_t units, NOT bytes. do not come for me later. 🙈

and that's the whole page, you ate it, go get that serial number 🫶

signing off from the Simple Directmedia Layer girlies 💜 — this is from SDL 3.4.18, and yeah, that's the version, that's the vibe, bye bestie 🌈⭐
