/*  FUNCTION
	Looks for the next dos list entry with the right name. The list
	must be locked for this. There may be not more than one device
	or assign node of the same name. There are no restrictions on
	volume nodes.

    INPUTS
	dlist - the value given by LockDosList() or the last call to
	        FindDosEntry().
	name  - logical device name without colon. Case insensitive.
	flags - the same flags as given to LockDosList() or a subset
	        of them.

    RESULT
	Pointer to dos list entry found or NULL if the are no more entries.
