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
       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 unde-
       fined.
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.
