# SDL\_GPUCommandBuffer(3type)

An opaque handle representing a command buffer.

## NAME

SDL\_GPUCommandBuffer - An opaque handle representing a command buffer.

## HEADER FILE

Defined in SDL3/SDL\_gpu.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**typedef struct SDL\_GPUCommandBuffer SDL\_GPUCommandBuffer;**

## DESCRIPTION

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 Once the command buffer is submitted, it is no longer valid to use it.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 only access a command buffer on the thread you acquired it from.

## AVAILABILITY

This struct is available since SDL 3.2.0.
