Simple window none-responsive

SDL Development
1

hi i just wrote my first sdl code and it compiles successfully but the window is not responsive and i have to use task manager to exit the program.

here is the code:

#include <SDL.h>

SDL_Window* g_pWindow = 0;
SDL_Renderer* g_pRenderer = 0;
bool g_bRunning = false;

bool init(const char* title, int xpos, int ypos, int
height, int width, int flags)
{
//initialize SDL
if (SDL_Init(SDL_INIT_EVERYTHING) >= 0)
{
// if succeeded create our window
g_pWindow = SDL_CreateWindow(title, xpos, ypos,
height, width, flags);

  // if the window creation succeeded create our
  // renderer
  if (g_pWindow != 0)
  {
  	g_pRenderer = SDL_CreateRenderer(g_pWindow, -1, 0);
  }
  else
  {
  	return false;
  }

  return true;

}
}

void render()
{
// set to black
SDL_SetRenderDrawColor(g_pRenderer, 0, 0, 0, 255);

// clear the window to black
SDL_RenderClear(g_pRenderer);

// show the window
SDL_RenderPresent(g_pRenderer);
}

int main(int argc, char* args[])
{
if (init(“Chapter 1: Setting up SDL”,
SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 640, 480, SDL_WINDOW_SHOWN))
{
g_bRunning = true;
}
else
{
return 1;
}

while (g_bRunning)
{
render();
}

// clean up SDL
SDL_Quit();

return 0;
}

You don’t appear to be calling SDL_PollEvent() anywhere, to respond to interaction events?

i’m reading this sdl book called sdl game development by shaun mitchell
but it’s badly put together and skips parts of code you’re supposed to write.
i’ll finish it but do you have better recommendation for beginner book?

I learned everything from Lazy Foo’s tutorials:
