Creates a transfer buffer to be used when uploading to or downloading from graphics resources.
Defined in <SDL3/SDL_gpu.h>
SDL_GPUTransferBuffer * SDL_CreateGPUTransferBuffer(
SDL_GPUDevice *device,const SDL_GPUTransferBufferCreateInfo *createinfo);
SDL_GPUDevice * | device | a GPU Context. |
const SDL_GPUTransferBufferCreateInfo * | createinfo | a struct describing the state of the transfer buffer to create. |
(SDL_GPUTransferBuffer *) Returns a transfer buffer on success, or NULL on failure; call SDL_GetError() for more information.
Download buffers can be particularly expensive to create, so it is good practice to reuse them if data will be downloaded regularly.
There are optional properties that can be provided through props
. These are the supported properties:
SDL_PROP_GPU_TRANSFERBUFFER_CREATE_NAME_STRING
: a name that can be displayed in debugging tools.This function is available since SDL 3.2.0.
