void * SDL_MapGPUTransferBuffer(
    SDL_GPUDevice *device,
    SDL_GPUTransferBuffer *transfer_buffer,
    bool cycle);

You must unmap the transfer buffer before encoding upload commands. The memory is owned by the graphics driver - do NOT call SDL_free() on the returned pointer.

device

transfer_buffer

cycle

if true, cycles the transfer buffer if it is already bound.

Returns the address of the mapped transfer buffer memory, or NULL on failure; call SDL_GetError() for more information.

This function is available since SDL 3.2.0.
