       memcpy - copy bytes in memory

SYNOPSIS

       #include <string.h>

       void *memcpy(void *restrict s1, const void *restrict s2, size_t n);

DESCRIPTION

       The  memcpy() function shall copy n bytes from the object pointed to by s2 into the object
       pointed to by s1. If copying takes place between objects that  overlap,  the  behavior  is
