That's your design issue to work out. Without some OpenSolaris project to work on here, I don't see how the rest of us can contribute to any meaningful degree. My apologies if your project really is open source available somewhere that I haven't seen, but this really isn't a proprietary product development support list. However, without looking at your code, one plausible way to do this would be to keep a linked list of per-instance data structures. Allocate those structures when the stream is opened, and insert them into a global list under a lock. When you open a v4 stream, look for a corresponding v6 stream already in the list, and link them together if found. When you open v6, do the same for v4. When a stream closes, check the other linked stream, and remove its pointer. That way, if you have one, you can always find the other. Be very careful about data structure access here and the object lifetime -- design the locking and access mechanisms carefully. It's surprisingly easy to hurt yourself on a multithreaded machine like Solaris. -- James Carlson, Solaris Networking <[EMAIL PROTECTED]> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 _______________________________________________ networking-discuss mailing list [email protected]
