✨ SDL_atof — bestie's guide to turning a string into a double ✨

okay so you know what's up: this is SDL_atof(3), part of the SDL3 FUNCTIONS crew, and she's here to parse a double out of a string for you. no drama, no fuss, just vibes and floating point 💅

🌸 NAME 🌸

SDL_atof — parse a double from a string. literally that's it, that's her job 🎀

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_stdinc.h>

double SDL_atof(const char *str);

one header, one function, one const char *, one double coming right back at you ✨

💖 DESCRIPTION 💖

the way that this one is so simple... 🥹

calling SDL_atof(str) is equivalent to calling SDL_strtod(str, NULL). that's the whole tea, bestie. same result, same energy, just a shorter name for when you don't need that second argument.

🧚 FUNCTION PARAMETERS 🧚

  • str — the null-terminated string you want it to read. must not be NULL — like, seriously, don't. 🫶

👑 RETURN VALUE 👑

you get back the parsed double. that's the prize, that's the crown, that's the whole point ⭐

🌈 THREAD SAFETY 🌈

it is safe to call this function from any thread. go wild, queen, thread it from everywhere 🔥

⭐ AVAILABILITY ⭐

this one's been around since SDL 3.2.0. vintage-ish but make it fresh 💜

🎀 SEE ALSO 🎀
