nn::applet::CTR::SetHomeButtonCallback Function

void SetHomeButtonCallback(
     AppletHomeButtonCallback callback,
     uptr arg = 0
);

	Name	Description
in	callback	Callback.
in	arg	Callback arguments.

None.

Sets the callback invoked when HOME is pressed.

The callback is called when a HOME Button press is detected.

A number of applet functions will not end until the process has left the callback, so promptly end the callback to reduce the risk of deadlock.

 Example
  bool myHomeButtonCallback( uptr arg, bool isActive, applet::HomeButtonState state )
  {
      NN_UNUSED_VAR(arg);
      if ( isActive )
      {
          if ( state == applet::HOME_BUTTON_SINGLE_PRESSED )
          {
             NN_LOG("HOME BUTTON is clicked.\n");
          }
          else
          {
             NN_LOG("HOME BUTTON is double-clicked.\n");
          }
          return true;
      }
      else
      {
          return false;
      }
  }
  nnMain()
  {
      applet::SetHomeButtonCallback( myHomeButtonCallback, 0 );
         …
  }
