SDL_PRIx64(3)

💅 SDL_PRIx64(3) — a lil' page from the SDL3 FUNCTIONS fam 🎀

okay bestie, sit down, hydrate, and let me tell you about the most lowkey iconic little macro in all of SDL. this is SDL_PRIx64, and she is serving exactly one job, and she does it flawlessly. no cap.

---

✨ NAME ✨

SDL_PRIx64 — a printf-formatting string for a Uint64 value as lower-case hexadecimal. 💜

that's it. that's the whole personality. and honestly? we love a girl who knows her lane.

---

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_stdinc.h>

#define SDL_PRIx64 "llx"

look at her. one include, one define. so clean, so minimal, so effortless. 🫶

🌸 DESCRIPTION 🌸

so here's the tea ☕: SDL_PRIx64 is a macro that expands to the format specifier you need to print a Uint64 as lower-case hexadecimal. it's giving "I gotchu, bestie, you don't have to guess what your platform's compiler thinks uint64_t is."

Use it like this:

SDL_Log("There are %" SDL_PRIx64 " bottles of beer on the wall.", bottles);

see how she slots right into that format string? % then the macro then the rest of your format spec. the way that works is literally just string-literal concatenation at compile time. so "%" and SDL_PRIx64 smoosh together into "%llx" before the compiler even blinks. ✨

and yeah — you could raw-dog %llx yourself if you want, but SDL_PRIx64 is the one that's portable and won't ghost you on some random architecture. iykyk. 🔥

no notes, no gotchas listed, no warnings. just a good girl doing a good job. 💖
