NAME

12       memmove - copy bytes in memory with overlapping areas
13

SYNOPSIS

15       #include <string.h>
16
17       void *memmove(void *s1, const void *s2, size_t n);
18
19

DESCRIPTION

21       The memmove() function shall copy n bytes from the object pointed to by
22       s2  into  the  object pointed to by s1. Copying takes place as if the n
23       bytes from the object pointed to by s2 are first copied into  a  tempo‐
24       rary  array  of n bytes that does not overlap the objects pointed to by
25       s1 and s2, and then the n bytes from the  temporary  array  are  copied
26       into the object pointed to by s1.
27

RETURN VALUE

29       The  memmove() function shall return s1; no return value is reserved to
30       indicate an error.
31
