# SDL_SubmitGPUCommandBuffer

Submits a command buffer so its commands can be processed on the GPU.

## Header File

Defined in [<SDL3/SDL_gpu.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_gpu.h)

## Syntax

```c
bool SDL_SubmitGPUCommandBuffer(
    SDL_GPUCommandBuffer *command_buffer);
```

## Function Parameters

|                                                |                    |                   |

| [SDL_GPUCommandBuffer](SDL_GPUCommandBuffer) * | **command_buffer** | a command buffer. |

## Return Value

(bool) Returns true on success, false on failure; call

All commands in the submission are guaranteed to begin executing before any
command in a subsequent submission begins executing.
