SDL_AUDIO_ISSIGNED(3)

💖 SDL_AUDIO_ISSIGNED(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, and today's main character is SDL_AUDIO_ISSIGNED — the little macro that tells you whether an SDL_AudioFormat is signed data or not. no cap, it's a one-liner and it's iconic for it. 🎀

---

✨ NAME ✨

SDL_AUDIO_ISSIGNED — figure out if an SDL_AudioFormat represents signed data. that's it, that's the whole job. 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_audio.h>

#define SDL_AUDIO_ISSIGNED(x)        ((x) & SDL_AUDIO_MASK_SIGNED)

literally just include the header and the macro is yours. so slay. ✨

---

🦋 DESCRIPTION 🦋

so here's the vibe: you hand it an SDL_AudioFormat and it tells you whether that format is signed. that's the whole deal.

for example — and this is the example, straight from the source, not me improvising:

SDL_AUDIO_ISSIGNED(SDL_AUDIO_U8) returns 0.

because SDL_AUDIO_U8 is unsigned, bestie. the U is right there in the name. 🙈

---

🎀 MACRO PARAMETERS 🎀

• x — an SDL_AudioFormat value. that's the thing you're vibe-checking. 👑

---

💜 RETURN VALUE 💜

returns non-zero if the format is signed, and zero otherwise. so it's giving "truthy or falsy" energy — don't count on it being exactly 1, just count on it being not-zero when signed. iykyk. ⭐

---

🔥 THREAD SAFETY 🔥

it is safe to call this macro from any thread. go wild, no locks needed, no drama. 🧚

---

🌈 AVAILABILITY 🌈

this macro has been available since SDL 3.2.0. so if you're on anything older, sorry babe, it's not there yet. 😭

---

reminder bestie: SDL_AUDIO_MASK_SIGNED is doing the actual bit-twiddling here, and the macro is literally just ((x) & SDL_AUDIO_MASK_SIGNED). don't rewrite it, don't "improve" it, just use it. periodt. 💅

and that's the whole page, my love 🫶 — brought to you by the lovely folks at Simple Directmedia Layer, from SDL 3.4.18, filed under SDL_AUDIO_ISSIGNED(3). mwah, go make some noise. 💖✨🎀
