The directory name could be set in /proc/sys/coredir (or somesuch) with an initial value of "." of course. Other than that I like the idea, although process "name" could get a lot of clashes on threads, and pid gets reused. There may be a better idea, but most of mine are cumbersome. This would really simplify certain kinds of dump analysis. -- bill davidsen "If I were a diplomat, in the best case I'd go hungry. In the worst case, people would die." -- Robert Lipe
