SDL_MS_TO_NS(3)

💖 SDL_MS_TO_NS 💖

okay bestie, welcome to the SDL_MS_TO_NS(3) page, part of the SDL3 FUNCTIONS collection ✨ it's short, it's sweet, it's a macro, and honestly? she's iconic for it 💅

---

✨ NAME ✨

SDL_MS_TO_NS — convert milliseconds to nanoseconds, no big deal 🦋

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_timer.h>

#define SDL_MS_TO_NS(MS)        (((Uint64)(MS)) * SDL_NS_PER_MS)

like. look at her. one line. does exactly what it says 🎀

---

💫 DESCRIPTION 💫

so here's the vibe check: this macro turns milliseconds into nanoseconds. that's the whole thing. that's the plot.

BUT — and this is the part where you gotta pay attention — it only converts whole numbers, not fractional milliseconds. so if you roll up with 1.5 ms expecting a cute little answer, that is not the energy here, bestie 😭 whole numbers only, periodt.

---

🫶 MACRO PARAMETERS 🫶

• MS — the number of milliseconds you wanna convert, babe. hand it over 💜

---

⭐ RETURN VALUE ⭐

it hands you back MS, but now expressed in nanoseconds. same number, glow-up edition ✨

---

🧚 THREAD SAFETY 🧚

you can call this macro from any thread and it's totally safe, no cap 🫶 no locks, no drama, no main character conflict. go off 👑

---

🌈 AVAILABILITY 🌈

this macro has been around since SDL 3.2.0 — so if you're on anything older, she's not there yet, sorry babe 🙈

---

lowkey obsessed with how a macro can be this simple and this useful at the same time. it's giving "does one thing and does it perfectly" 💅🔥
