# SDL_GPUCompareOp

Specifies a comparison operator for depth, stencil and sampler operations.

## 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_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 3.1.3
