PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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.
