✨ SDL_ultoa ✨

okay bestie, welcome to `SDL_ultoa(3) — straight out of the SDL3 FUNCTIONS section of the manual, and honestly? it's giving "tiny function, big personality." 🎀

🌸 NAME 🌸

SDL_ultoa — Convert an unsigned long integer into a string. 💅

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_stdinc.h>

char * SDL_ultoa(unsigned long value, char *str, int radix);

💖 DESCRIPTION 💖

okay so here's the tea, bestie: this one needs a radix, like, you have to specify it for the string format. no radix, no vibe check, no output. 🙈

  • specify 10 → you get a decimal number ✨
  • specify 16 → you get hexadecimal 💜
  • etc. etc., you get the picture 🎀
  • and it must be in the range of 2 to 36. that's the whole window, no exceptions, periodt.
⚠️ okay but FR FR, listen up: this function will overflow a buffer if str is not large enough to hold the output! like, it will just keep writing. it does not care. it is not checking. 😭

so if you'd rather not experience that particular jump scare, it may be safer to use SDL_snprintf to clamp output, or SDL_asprintf to allocate a buffer. 🫶

otherwise, honestly? it doesn't hurt to allocate much more space than you expect to use. like, spoil yourself. go big. and don't forget null terminator bytes, etc. — those little guys count too. 💀

🌈 FUNCTION PARAMETERS 🌈

  • value — the unsigned long integer to convert. the main character, the one we're turning into a string 👑
  • str — the buffer to write the string into. this is where the magic lands, so make it roomy bestie 🎀
  • radix — the radix to use for string generation. base 2 to base 36, pick your fighter ⭐

💜 RETURN VALUE 💜

Returns str. that's it. it hands you back the same buffer you gave it. iconic, honestly. 💅

🧚 THREAD SAFETY 🧚

It is safe to call this function from any thread. 🌈 no drama, no locks, no fighting, we love a peaceful queen. ✨

⭐ AVAILABILITY ⭐

This function is available since SDL 3.2.0. 🎀
