sdlMapGpuTransferBuffer function gpu
Pointer<NativeType>
sdlMapGpuTransferBuffer(
- Pointer<
SdlGpuDevice> device, - Pointer<
SdlGpuTransferBuffer> transferBuffer, - bool cycle
Maps a transfer buffer into application address space.
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.
\param device a GPU context. \param transfer_buffer a transfer buffer. \param 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.
\since This function is available since SDL 3.2.0.
