# SDL_GPUStencilOp

Specifies what happens to a stored stencil value if stencil tests fail or pass.

## Header File

Defined in [<SDL3/SDL_gpu.h>](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;
```
