I wrote a wifi application which communicates with my pc.
How can i send a message to my pc when the application is left (HOME --> yes)? I know how to send messages but i dont know how i know that the application is left.

You should already know how to setup a callback thread...if not refer to the file "pspdev\psp\sdk\samples\gu\common\callbacks.c".
In function exitCallback() insert your own code:

Code:
int exitCallback(int arg1, int arg2, void *common)
{
        // do whatever you want here
   exitRequest = 1; // main program loops should check for exitRequest
   return 0;
}

void main()
{
  while(!exitRequest)
  {
      // ...
  }
  sceKernelExitGame();
}



Grab any other wifi specific code from sdk examples....

Good luck,
jean

Code:
int exit_callback(int arg1, int arg2, void *common)
{
        write(new, "exiting", strlen("exiting"));
   sceKernelExitGame();
   return 0;
}

I already tried exactly that code but it exits without sending anything

....i bet it's not "exactly" the same.
1) don't know of all the code around to register the exit handler you wrote
2) you should NOT use sceKernelExitGame() from inside the exit handler, but instead accordingly set a variable that main loop checks against.
3) you start a communication routine a millisecond before the program context gets cleaned because of the issued exit command...At least put a sleep after the string printout.

PS: if you post some critical points of your code, this could help us helping you.
