/***
*char *strncpy(dest, source, count) - copy at most n characters
*
*Purpose:
*       Copies count characters from the source string to the
*       destination.  If count is less than the length of source,
*       NO NULL CHARACTER is put onto the end of the copied string.
*       If count is greater than the length of sources, dest is padded
*       with null characters to length count.
*
*
*Entry:
*       char *dest - pointer to destination
*       char *source - source string for copy
*       unsigned count - max number of characters to copy
*
*Exit:
*       returns dest
*
*Exceptions:
*
