###### (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_GPUCompareOp Specifies a comparison operator for depth, stencil and sampler operations. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_gpu.h) ## Syntax ```c typedef enum SDL_GPUCompareOp { SDL_GPU_COMPAREOP_INVALID, SDL_GPU_COMPAREOP_NEVER, /**< The comparison always evaluates false. */ SDL_GPU_COMPAREOP_LESS, /**< The comparison evaluates reference < test. */ SDL_GPU_COMPAREOP_EQUAL, /**< The comparison evaluates reference == test. */ SDL_GPU_COMPAREOP_LESS_OR_EQUAL, /**< The comparison evaluates reference <= test. */ SDL_GPU_COMPAREOP_GREATER, /**< The comparison evaluates reference > test. */ SDL_GPU_COMPAREOP_NOT_EQUAL, /**< The comparison evaluates reference != test. */ SDL_GPU_COMPAREOP_GREATER_OR_EQUAL, /**< The comparison evalutes reference >= test. */ SDL_GPU_COMPAREOP_ALWAYS /**< The comparison always evaluates true. */ } SDL_GPUCompareOp; ``` ## Version This enum is available since SDL 3.0.0 ## See Also - [SDL_CreateGPUGraphicsPipeline](SDL_CreateGPUGraphicsPipeline) ---- [CategoryAPI](CategoryAPI), [CategoryAPIEnum](CategoryAPIEnum), [CategoryGPU](CategoryGPU)
