SDL_DispatchGPUComputeIndirect - Man Page

Defined in SDL3/SDL_gpu.h

#include "SDL3/SDL.h"

void SDL_DispatchGPUComputeIndirect(
    SDL_GPUComputePass *compute_pass,
    SDL_GPUBuffer *buffer,
    Uint32 offset);

The buffer layout should match the layout of

SDL_GPUIndirectDispatchCommand . You must not call this function before binding a compute pipeline.

A VERY IMPORTANT NOTE If you dispatch multiple times in a compute pass, and the dispatches write to the same resource region as each other, there is no guarantee of which order the writes will occur. If the write order matters, you MUST end the compute pass and begin another one.

compute_pass

a compute pass handle.

buffer

a buffer containing dispatch parameters.

offset

the offset to start reading from the dispatch buffer.

This function is available since SDL 3.2.0.
