 +=====SDL=====
  
 +This is my write-up on my working with SDL, from the SDL book __Focus on SDL__. 
 +
 +The first program in the book just checks to see if SDL initialized properly:
 +
 +fosdl1_1.cpp
 +
 +<code c>
 +  1 #include "SDL/SDL.h"
 +  2 #include <stdio.h>
 +  3 
 +  4 int main(int argc, char* argv[])
 +  5 {
 +  6     if (SDL_Init(SDL_INIT_VIDEO) == -1)
 +  7     {
 +  8         fprintf(stderr, "Could not initialize SDL!\n");
 +  9     }
 + 10     else
 + 11     {
 + 12         fprintf(stdout, "SDL initialized properly!\n");
 + 13         SDL_Quit();
 + 14     }
 + 15     return 0;
 + 16 }
 +</code>
 +
 +The next program is a small SDL-based application, a screen pops up when it is run:
 +
 +fosdl1_2.cpp
 +
 +<code c>
 +  1 #include "SDL/SDL.h"
 +  2 #include <stdio.h>
 +  3 #include <stdlib.h>
 +  4 
 +  5 SDL_Surface* g_pMainSurface = NULL;
 +  6 SDL_Event g_Event;
 +  7 
 +  8 int main(int argc, char* argv[])
 +  9 {
 + 10     if (SDL_Init(SDL_INIT_VIDEO) == -1)
 + 11     {
 + 12         fprintf(stderr, "Could not initialize SDL!\n");
 + 13         exit(1);
 + 14     }
 + 15     else
 + 16     {
 + 17         fprintf(stdout, "SDL initialized properly!\n");
 + 18         atexit(SDL_Quit);
 + 19     }
 + 20 
 + 21     g_pMainSurface = SDL_SetVideoMode( 640,480, 0, SDL_ANYFORMAT);
 + 22 
 + 23     if(!g_pMainSurface)
 + 24     {
 + 25         fprintf(stderr, "Could not create main surface!\n");
 + 26         exit(1);
 + 27     }
 + 28 
 + 29     for(;;)
 + 30     {
 + 31         if(SDL_WaitEvent(&g_Event) == 0)
 + 32         {
 + 33             fprintf(stderr, "Error while waiting for an event!\n");
 + 34             exit(1);
 + 35         }
 + 36 
 + 37         //check the type of event
 + 38         if(g_Event.type == SDL_QUIT)
 + 39         {
 + 40             fprintf(stdout, "Quit event has occured.\n");
 + 41             break;
 + 42         }
 + 43     }
 + 44 
 + 45     fprintf(stdout, "Terminating program normally.\n");
 + 46 
 + 47     return(0);
 + 48 }
 +</code>
 +
 +But wait! There's more... Coming Soon!
