Description

   The memccpy function operates on strings in memory areas. A
   memory area is a group of contiguous characters bound by a count
   and not terminated by a null character. The function does not
   check for overflow of the receiving memory area. The memccpy
   function is defined in the <string.h> header file.

   The memccpy function sequentially copies characters from the
   location pointed to by source into the location pointed to by
   dest until one of the following occurs:

   o  The character specified by c (converted to an unsigned char)
      is copied.

   o  The number of characters specified by n is copied.
