memmove(3) Library Functions Manual memmove(3)
NAME
memmove - copy memory area
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <string.h>
void *memmove(void dest[.n], const void src[.n], 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.
RETURN VALUE
The memmove() function returns a pointer to dest.
