#include <string.h>void *memcpy(void *to, const void *from, size_t count);
The memcpy( ) function copies count characters from the array pointed to by from into the array pointed to by to. If the arrays overlap, the behavior of memcpy( ) is undefined.
In C99, to and from are qualified by restrict.
The memcpy( ) function returns a pointer to to.
A related function is memmove( ).
