[dtrace-discuss] Re: How to get absolute path?

[Steve Peters]

Ian,
You'll find fewer "missing pieces" in the next Mac OS X Leopard Seed  
Release (I take it you're a registered Apple developer eligible for  
seeding.) And you'll find fewer yet in the GM Leopard. The challenge  
in constructing a full path from a DTrace action comes when you try to  
traverse vnodes -- that usually requires taking a lock.
