C++17(C11)): Bounds-checking memcpy_s() and memmove_s()

C++17 added the bounds-checking functions memcpy_s() and memmove_s().

#include <algorithm>
#include <cstring>
#include <iostream>
using namespace std;

int main()
{
  char   jklmnop[ ] = "jklmnop";
  char   buffer1[7] = {0};
  char   buffer2[7] = {0};
 
  memcpy_s(buffer1, sizeof(buffer1), jklmnop,
           min(sizeof(buffer1), sizeof(jklmnop)));
  buffer1[6] = '\0';
  cout << buffer1 << " "; // jklmno

  memcpy_s(buffer2, sizeof(buffer2), jklmnop,
           min(sizeof(buffer1), sizeof(buffer2)));
  buffer2[6] = '\0';
  cout << buffer1 << " "; // jklmno
  cout << buffer2 << " "; // jklmno

  memmove_s(buffer2, sizeof(buffer2), jklmnop,
            min(sizeof(buffer1), sizeof(buffer2)));
  buffer2[6] = '\0';
  cout << buffer1 << " "; // jklmno
  cout << buffer2 << " "; // jklmno

  cout << endl;
  return 0;
}
// Output: jklmno jklmno jklmno jklmno jklmno
