- * vl_comp - compare the names of two virtual links

- * VL_COMP compares the names of two links. It returns
- * 0 if they are equal, negative if vl1 < vl2, and positive if
- * vl1 > vl2.
- *
- * ARGS: vl1,vl2 - Virtual links to be compared
- *
- * RETURNS: 0 if equal, + is vl1 > vl2, - if vl1 < vl2
- *
- * NOTES: Order of significance is as follows. Existence,
- * name. If names do not exist, then hosttype, host,
- * native filenametype, native filename. The only time
- * the name will not exist if if the link is a union link.
