memcpy - copy memory area

#include <string.h>

void *memcpy(void *dest, const void *src, size_t n);

The memcpy() function copies n bytes from memory area src to memory area dest. The memory areas must not overlap. Use memmove(3) if the memory areas do overlap.

The memcpy() function returns a pointer to dest.
