What exactly would I put in here?
It calls into my code with
void DisplayReconfigurationCallBack (CGDirectDisplayID display,
CGDisplayChangeSummaryFlags flags, void *userInfo)
{
if (flags & kCGDisplayAddFlag)
{
// do stuff
}
else if (flags & kCGDisplayRemoveFlag)
{
// do different stuff
}
}
Assuming my code does not do anything untold, what could the system do that
would cause it to fail?
