When you call SDL_BindGPUVertexBuffers , you specify the binding slots of the vertex buffers. For example if you called

SDL_BindGPUVertexBuffers
with a first_slot of 2 and num_bindings of 3, the binding slots 2, 3, 4 would be used by the vertex buffers you pass in.

Vertex attributes are linked to buffers via the buffer_slot field of

SDL_GPUVertexAttribute . For example, if an attribute has a buffer_slot of 0, then that attribute belongs to the vertex buffer bound at slot 0.

This struct is available since SDL 3.2.0.
