                       int x1, int y1, int x2, int y2);
```

## Function Parameters

|                                |              |                                      |
| ------------------------------ | ------------ | ------------------------------------ |
| [SDL_Renderer](SDL_Renderer) * | **renderer** | the rendering context.               |
| int                            | **x1**       | the x coordinate of the start point. |
| int                            | **y1**       | the y coordinate of the start point. |
| int                            | **x2**       | the x coordinate of the end point.   |
| int                            | **y2**       | the y coordinate of the end point.   |

## Return Value

(int) Returns 0 on success or a negative error code on failure; call
[SDL_GetError](SDL_GetError)() for more information.

## Remarks

[SDL_RenderDrawLine](SDL_RenderDrawLine)() draws the line to include both
end points. If you want to draw multiple, connecting lines use
[SDL_RenderDrawLines](SDL_RenderDrawLines)() instead.

## Version

This function is available since SDL 2.0.0.
