# SDL_GPUVertexAttribute
A structure specifying a vertex attribute.
## Header File
Defined in [<SDL3/SDL_gpu.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_gpu.h)
## Syntax
```c
typedef struct SDL_GPUVertexAttribute
{
Uint32 location; /**< The shader input location index. */
Uint32 buffer_slot; /**< The binding slot of the associated vertex buffer. */
SDL_GPUVertexElementFormat format; /**< The size and type of the attribute data. */
Uint32 offset; /**< The byte offset of this attribute relative to the start of the vertex element. */
} SDL_GPUVertexAttribute;
```
## Remarks
All vertex attribute locations provided to an
[SDL_GPUVertexInputState](SDL_GPUVertexInputState) must be unique.
## Version
This struct is available since SDL 3.2.0.
