memmove - copy memory area
#include <string.h> void *memmove(void *dest, const void *src, size_t n);
DESCRIPTIONThe memmove() function copies n bytes from memory area src to memory area dest. The memory areas may overlap: copying takes place as though the bytes in src are first copied into a temporary array that does not overlap src or dest, and the bytes are then copied from the temporary array to dest.
RETURN VALUEThe memmove() function returns a pointer to dest.
