int SDL_RenderDrawLine(SDL_Renderer * renderer,
                       int x1, int y1, int x2, int y2);

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.

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

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