###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!) # SDL_UploadToGPUBuffer Uploads data from a transfer buffer to a buffer. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_gpu.h) ## Syntax ```c void SDL_UploadToGPUBuffer( SDL_GPUCopyPass *copy_pass, const SDL_GPUTransferBufferLocation *source, const SDL_GPUBufferRegion *destination, bool cycle); ``` ## Function Parameters | | | | | ---------------------------------------------------------------------- | --------------- | --------------------------------------------------------------------------------- | | [SDL_GPUCopyPass](SDL_GPUCopyPass) * | **copy_pass** | a copy pass handle. | | const [SDL_GPUTransferBufferLocation](SDL_GPUTransferBufferLocation) * | **source** | the source transfer buffer with offset. | | const [SDL_GPUBufferRegion](SDL_GPUBufferRegion) * | **destination** | the destination buffer with offset and size. | | bool | **cycle** | if true, cycles the buffer if it is already bound, otherwise overwrites the data. | ## Remarks The upload occurs on the GPU timeline. You may assume that the upload has finished in subsequent commands. ## Version This function is available since SDL 3.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryGPU](CategoryGPU)
