*Purpose:
*	Increment the supplied string pointer by the specified number

*
*Entry:
*	const unsigned char *string = pointer to string
*	unsigned int ccnt = number of char to advance the pointer
*
*Exit:
*	Returns pointer after advancing it.
*	Returns pointer to end of string if string is not ccnt chars long.
*	Returns NULL is supplied pointer is NULL.
