An opaque handle representing a command buffer.
Defined in <SDL3/SDL_gpu.h>
typedef struct SDL_GPUCommandBuffer SDL_GPUCommandBuffer;
Most state is managed via command buffers. When setting state using a command buffer, that state is local to the command buffer.
Commands only begin execution on the GPU once SDL_SubmitGPUCommandBuffer is called. Once the command buffer is submitted, it is no longer valid to use it.
Command buffers are executed in submission order. If you submit command buffer A and then command buffer B all commands in A will begin executing before any command in B begins executing.
In multi-threading scenarios, you should only access a command buffer on the thread you acquired it from.
This struct is available since SDL 3.1.3
