How to copy network files using C++

Question

I am trying to copy a file from a server to my machine, simply the code runs, does not return me any error, but does not copy the file.

Follow the code C++:

#include <iostream>
#include <windows.h>

using namespace std;

int main()
{
 CopyFile("\\\\server\\Teste\\arquivo.pdf","\\\\MeuPc\\c$\\arquivo.pdf",true);
}
