###### (This is the legacy documentation for SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) # SDL_RenderDrawLine Draw a line on the current rendering target. ## Header File Defined in [SDL_render.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_render.h) ## Syntax ```c int SDL_RenderDrawLine(SDL_Renderer * renderer, 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. ## See Also - [SDL_RenderDrawLines](SDL_RenderDrawLines) - [SDL_RenderDrawPoint](SDL_RenderDrawPoint) - [SDL_RenderDrawPoints](SDL_RenderDrawPoints) - [SDL_RenderDrawRect](SDL_RenderDrawRect) - [SDL_RenderDrawRects](SDL_RenderDrawRects) - [SDL_RenderFillRect](SDL_RenderFillRect) - [SDL_RenderFillRects](SDL_RenderFillRects) - [SDL_RenderPresent](SDL_RenderPresent) - [SDL_SetRenderDrawBlendMode](SDL_SetRenderDrawBlendMode) - [SDL_SetRenderDrawColor](SDL_SetRenderDrawColor) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryRender](CategoryRender)
