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
       memccpy -- copy bytes in memory

SYNOPSIS
       #include <string.h>

       void *memccpy(void *restrict s1, const void *restrict s2,
	   int c, size_t n);

DESCRIPTION
       The memccpy() function shall copy bytes from memory area s2 into s1, stopping after the	first  occurrence  of  byte  c	(converted  to	an
       unsigned  char)	is  copied,  or  after n bytes are copied, whichever comes first. If copying takes place between objects that overlap, the
       behavior is undefined.

RETURN VALUE
       The memccpy() function shall return a pointer to the byte after the copy of c in s1, or a null pointer if c was not found in  the  first  n
       bytes of s2.

ERRORS
       No errors are defined.

       The following sections are informative.

EXAMPLES
       None.

APPLICATION USAGE
       The memccpy() function does not check for the overflow of the receiving memory area.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
