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

       No errors are defined.

       memccpy — copy bytes in memory

       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.

       None.

       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.
