NAME

6       memmove - copy bytes in memory with overlapping areas
7

SYNOPSIS

10
11       void *memmove(void *s1, const void *s2, size_t n);

DESCRIPTION

15       The memmove() function shall copy n bytes from the object pointed to by
16       s2 into the object pointed to by s1. Copying takes place as  if  the  n
17       bytes  from  the object pointed to by s2 are first copied into a tempo‐
18       rary array of n bytes that does not overlap the objects pointed  to  by
19       s1  and  s2,  and  then the n bytes from the temporary array are copied
20       into the object pointed to by s1.
21

RETURN VALUE

23       The memmove() function shall return s1; no return value is reserved  to
24       indicate an error.
