PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       memcpy - copy bytes in memory
SYNOPSIS
       #include <string.h>
       void *memcpy(void *restrict s1, const void *restrict s2, size_t n);

DESCRIPTION
       The memcpy() function shall copy n bytes from the object pointed to  by
       s2  into  the  object  pointed to by s1. If copying takes place between
       objects that overlap, the behavior is undefined.
RETURN VALUE
       The memcpy() function shall return s1; no return value is  reserved  to
       indicate an error.
ERRORS
       No errors are defined.
       The following sections are informative.
EXAMPLES
       None.
APPLICATION USAGE
       The  memcpy() function does not check for the overflow of the receiving
       memory area.
RATIONALE
       None.
FUTURE DIRECTIONS
       None.
