(This is the documentation for SDL3, which is under heavy development and the API is changing! SDL2 is the current stable version!)

SDL_GPUCommandBuffer

An opaque handle representing a command buffer.

Header File

Syntax

typedef struct SDL_GPUCommandBuffer SDL_GPUCommandBuffer;

Remarks

Most state is managed via command buffers. When setting state using a command buffer, that state is local to the command buffer.

Commands only begin execution on the GPU once SDL_SubmitGPUCommandBuffer is called. Once the command buffer is submitted, it is no longer valid to use it.

Command buffers are executed in submission order. If you submit command buffer A and then command buffer B all commands in A will begin executing before any command in B begins executing.

In multi-threading scenarios, you should acquire and submit a command buffer on the same thread. As long as you satisfy this requirement, all functionality related to command buffers is thread-safe.

Version

This struct is available since SDL 3.0.0
