###### (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_GPUStencilOp Specifies what happens to a stored stencil value if stencil tests fail or pass. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_gpu.h) ## Syntax ```c typedef enum SDL_GPUStencilOp { SDL_GPU_STENCILOP_INVALID, SDL_GPU_STENCILOP_KEEP, /**< Keeps the current value. */ SDL_GPU_STENCILOP_ZERO, /**< Sets the value to 0. */ SDL_GPU_STENCILOP_REPLACE, /**< Sets the value to reference. */ SDL_GPU_STENCILOP_INCREMENT_AND_CLAMP, /**< Increments the current value and clamps to the maximum value. */ SDL_GPU_STENCILOP_DECREMENT_AND_CLAMP, /**< Decrements the current value and clamps to 0. */ SDL_GPU_STENCILOP_INVERT, /**< Bitwise-inverts the current value. */ SDL_GPU_STENCILOP_INCREMENT_AND_WRAP, /**< Increments the current value and wraps back to 0. */ SDL_GPU_STENCILOP_DECREMENT_AND_WRAP /**< Decrements the current value and wraps to the maximum value. */ } SDL_GPUStencilOp; ``` ## Version This enum is available since SDL 3.0.0 ## See Also - [SDL_CreateGPUGraphicsPipeline](SDL_CreateGPUGraphicsPipeline) ---- [CategoryAPI](CategoryAPI), [CategoryAPIEnum](CategoryAPIEnum), [CategoryGPU](CategoryGPU)
