###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!)
# SDL_GPUBufferUsageFlags

Specifies how a buffer is intended to be used by the client.

## Header File

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

## Syntax

```c
typedef Uint32 SDL_GPUBufferUsageFlags;

#define SDL_GPU_BUFFERUSAGE_VERTEX                (1u << 0) /**< Buffer is a vertex buffer. */
#define SDL_GPU_BUFFERUSAGE_INDEX                 (1u << 1) /**< Buffer is an index buffer. */
#define SDL_GPU_BUFFERUSAGE_INDIRECT              (1u << 2) /**< Buffer is an indirect buffer. */
#define SDL_GPU_BUFFERUSAGE_GRAPHICS_STORAGE_READ (1u << 3) /**< Buffer supports storage reads in graphics stages. */
#define SDL_GPU_BUFFERUSAGE_COMPUTE_STORAGE_READ  (1u << 4) /**< Buffer supports storage reads in the compute stage. */
#define SDL_GPU_BUFFERUSAGE_COMPUTE_STORAGE_WRITE (1u << 5) /**< Buffer supports storage writes in the compute stage. */
```

## Remarks

A buffer must have at least one usage flag. Note that some usage flag
combinations are invalid.

## Version

This enum is available since SDL 3.0.0
