NAME

memmove - copy memory area

SYNOPSIS

#include <string.h>

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

DESCRIPTION

The 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.
