Basically, my layout is that I have my main() thread doing the actual code needed..but for now, it just clears the screen and goes to an infinite loop waiting for the quit_all variable to change to 1 Then I have a SDL thread made for checking and handling the messages of the video display.
here is the main points of my code...(condensed)
Code: Select all
int Thread_Messaging(void * arg){
if( SDL_Init(SDL_INIT_VIDEO) == -1 ){exit(1);}
display.screen=SDL_SetVideoMode(640,480,8,SDL_HWSURFACE);
display.vbuffer=new char[640*480*1];
volatile unsigned int quit=0;
while(quit==0){
display.FlushBuffer();
display.Render();
if(SDL_PollEvent(&event)==1){
switch(event.type){
case SDL_QUIT:
quit=1;
quit_all=1;
exit(0);
break;
}
}else{
//SDL_Delay(50); //don't waste all the processing time..
}
}
quit_all=1;
//SDL_QuitSubSystem(SDL_INIT_VIDEO);
//while(quit_all==1){}
SDL_Quit();
//exit(0);
//while(1){}
}
int main(int argc,char **argv)
#endif
{
// initialize SDL video
fprintf(stderr,"y");
if ( SDL_Init( SDL_INIT_EVENTTHREAD ) < 0 )
{
cout<< "Unable to init SDL: " << SDL_GetError() << endl;
exit(1);
}
// if( SDL_Init(SDL_INIT_VIDEO) == -1 ){exit(1);}
// make sure SDL cleans up before exit
//atexit(SDL_Quit);
// create a new window
messaging=SDL_CreateThread(Thread_Messaging,0);
//disk_cache=SDL_CreateThread(Thread_DiskCache,0);
fprintf(stderr,"t");
cout << "Waiting for SDL...";
SDL_Delay(1000);
cout << endl <<"done!";
DoRobots();
// all is well ;)
while(quit_all==0){
if(quit_all==1){
quit_all++;
SDL_WaitThread(messaging, 0);
SDL_Quit();
}
} //infinite loop...
//while(1){}
return 0;
}
