If all allocated threads are occupied while a new task comes in, then it creates a new thread, as offering a new task to a SynchronousQueue always fails when there is no one on the other end to accept it!

When to use inline function and when not to use it?
...iron reason to avoid inlining a function. The implementation is obliged to allocate a single static object for each function static whether or not the function is declared inline or not. Classes are still extensible if they have inline constructors and virtual destructors. And empty brace destructor...

How do pointer to pointers work in C?
... *p = 5;
return 1;//success
}
int get1024HeapMemory(int **p)
{
*p = malloc(1024);
if(*p == 0)
return -1;//error
else
return 0;//success
}
And you call it like this:
int x;
getValueOf5(&x);//I want to fill the int varaible, so I pass it's address in
//At this point x holds 5...
