memmove - copy memory area
#include <string.h>
void *memmove(void *dest, const void *src, size_t n);
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.
The
memmove() function returns a pointer to
dest.
