# SDL_GPUVertexAttribute A structure specifying a vertex attribute. ## Header File Defined in [](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. ## See Also - [SDL_GPUVertexBufferDescription](SDL_GPUVertexBufferDescription) - [SDL_GPUVertexInputState](SDL_GPUVertexInputState) - [SDL_GPUVertexElementFormat](SDL_GPUVertexElementFormat) ---- [CategoryAPI](CategoryAPI), [CategoryAPIStruct](CategoryAPIStruct), [CategoryGPU](CategoryGPU)
