Explain this single line of code

Scheduler::instance().clock()

Can anyone explain what this line of code means

Thanks in advance

What i understand is clock is function of class instance
and :: is scope operator which specifies instance and clock belongs to Scheduler class

Is it C++ or java?
Scheduler is a class, instance() is a function which will probably give/return an instance of that class and .clock() will invoke the function named clock of that particular instance (of class Scheduler).
But hard to say more without knowing your environment.

It is C++

Thanks for the reply

What does this means Packet* p = alloc();
if (n > 0)
p->allocdata(n);
return(p);
