(See > http:\\java.sun.com) I had a thought the other day re this and was wondering if it would work... With SYSV memory sharing, you can share memory between processes. A program image contains text regions and data regions. Now suppose you had a way of creating a shared memory region just big enough to hold your data image, and then mapping your data image into it. And your heap, if possible, (so malloc()'d data could be shared). Voila, now you can fork() a new thread... I'm not familiar with how object files are linked (relocatable data segments?) etc., but it *seems* like it would be easy... -Archie _______________________________________________________________________________ Archie L.
