SDL_InsertGPUDebugLabel(3)

💖 SDL_InsertGPUDebugLabel(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, and today's main character is SDL_InsertGPUDebugLabel 🎀

---

✨ NAME ✨

SDL_InsertGPUDebugLabel — drops an arbitrary string label straight into the command buffer callstream, no cap 💅

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_gpu.h>

void SDL_InsertGPUDebugLabel(
    SDL_GPUCommandBuffer *command_buffer,
    const char *text);

---

✨ DESCRIPTION ✨

ngl, this one is useful for debugging 🦋 that's literally the whole vibe. you slap a label in there and suddenly your GPU timeline is giving readable instead of giving mystery soup 😭

BUT — and this is the part where you need to lock in — on Direct3D 12, using SDL_InsertGPUDebugLabel requires WinPixEventRuntime.dll to be in your PATH or in the same directory as your executable. ✨

🚨 if that DLL is not findable, bestie, it's not gonna work. go get it. the instructions for how to obtain it live here: ⟨https://devblogs.microsoft.com/pix/winpixeventruntime/⟩ 👑

✨ FUNCTION PARAMETERS ✨

• command_buffer — a command buffer. that's it. that's the whole description. the command buffer in question 🫶
• text — a UTF-8 string constant to insert as the label. UTF-8! string constant! don't be out here passing random garbage, it said constant for a reason 🌸

---

✨ AVAILABILITY ✨

this icon is available since SDL 3.2.0 ⭐ so if you're on something older... it's giving deprecated-adjacent, upgrade era 💀

---

and that's the whole page, bestie!! 🌈 this came to you from the lovely people at Simple Directmedia Layer, running version SDL 3.4.18, and honestly? they ate. periodt. 💅💖✨🎀🦋
