SDL_SubmitGPUCommandBuffer(3)

💅 NAME 💅

okay bestie, so SDL_SubmitGPUCommandBuffer — it submits a command buffer so its commands can actually be processed on the GPU. that's it, that's the whole job, and it ate. ✨

---

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_gpu.h>

bool SDL_SubmitGPUCommandBuffer(
    SDL_GPUCommandBuffer *command_buffer);

---

🌸 DESCRIPTION 🌸

so here's the tea, and lowkey this part matters a LOT: once you call this, it is invalid to use the command buffer again. like, gone, done, no takebacks. do not touch it. 💀

also — and this is the part people always forget and then get confused — this must be called from the thread the command buffer was acquired on. same thread, no exceptions, no "but my thread pool tho". 🙈

and the ordering guarantee, which is genuinely iconic: all commands in the submission are guaranteed to begin executing before any command in a subsequent submission begins executing. so your vibes stay in order, fr fr. 👑
