Hmmmm... Not only is that undocumented SPI, but it's also used incorrectly. The comment about MDD PowerMacs is also wildly misleading.
In what sense is it used incorrectly? And how is the comment about MDD PowerMacs misleading? Not being combative; I honestly would like to understand where you're coming from there.
Think about it. Default C return type with no prototype is... And you cast that to... And suppose the real returned value is in another register...
Sorry, I forgot to include the prototype in my reply:
extern double CGSSecondsSinceLastInputEvent(unsigned long evType);

Here's some GPL code from Adium:
//Returns the current # of seconds the user has been idle
- (double)currentIdleTime
{
double idleTime = CGSSecondsSinceLastInputEvent(-1);
//On MDD Powermacs, the above function will return a large value when the machine is active (-1?).
//Here we check for that value and correctly return a 0 idle time.
if(idleTime >= 18446744000.0) idleTime = 0.0; //18446744073.0
return(idleTime);

Hello,
How can I get the system idle time in Cocoa? I want to know how long the user has been away from computer. I tried using a timer called EventLoopIdleTimer in Carbon, which works fine, but it only gives me the idle time of my application. I also read something about HIDIdleTime in the archives, but couldn't find any source code examples on how to use it.
Cheers,
Mike
