Array.Copy vs Buffer.BlockCopy
...uffer from one or more severe technical flaws, including not moving memory allocations out of the test loops (which introduces severe GC artifacts), not testing variable vs. deterministic execution flows, JIT warmup, and not tracking intra-test variability.

How do pointer to pointers work in C?
... *p = 5;
return 1;//success
}
int get1024HeapMemory(int **p)
{
*p = malloc(1024);

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...
What is external linkage and internal linkage?
...tructed due to issues with global construction order and can't dynamically allocate it using new while more in-depth initialization schemes may be beyond what is necessary for the object in question; by implication, this is mainly an issue on embedded systems that use C++).
