###### (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development 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), but apps should _only_ `#include "SDL.h"`! ## Syntax ```c int SDL_RenderDrawLine(SDL_Renderer * renderer, int x1, int y1, int x2, int y2); ``` ## Function Parameters | | | | ---------------- | ----------------------------------- | | **renderer** | the rendering context | | **x1** | the x coordinate of the start point | | **y1** | the y coordinate of the start point | | **x2** | the x coordinate of the end point | | **y2** | the y coordinate of the end point | ## Return Value 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)
