PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux

NAME

12       memcpy - copy bytes in memory
13

SYNOPSIS

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

DESCRIPTION

21       The memcpy() function shall copy n bytes from the object pointed to  by
22       s2  into  the  object  pointed to by s1. If copying takes place between
23       objects that overlap, the behavior is undefined.
24

RETURN VALUE

26       The memcpy() function shall return s1; no return value is  reserved  to
27       indicate an error.
28

ERRORS

30       No errors are defined.

39       memory area.
