memmove - copy memory area
Standard C library (libc, -lc)
#include <string.h>
void *memmove(void dest[.n], const void src[.n], 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.
For an explanation of the terms used in this section, see attributes(7).
