A group here is working on a project using a SUN in an embedded real-time
application involving communicating processes.
When they get to debugging this they are likely to ask for a multi-process
debugger. The kind of thing I'm thinking of is the ability to apply a dbx
or dbxtool type operation to multiple processes, stopping all the
processes when any one of them hits a breakpoint, ........ etc.
Has anyone come across anything like this ? Please mail me any pointers
and I'll summarise if I get any number of "I'd like to hear about too"
messages.
(If you have the source for just such a thing, please let me know about
it, but don't mail it yet, in case there are a lot of them out there !)

Try to get a copy of STB 1989-05, the May 1989 Software Technical Bulletin. On pages 643-644 it discusses using dbx/dbxtool on a child process. It says 1) link with the -N flag, 2) put a sleep(20) call in the child process path, 3) put a breakpoint in the parent process path after the child process ID is available, 4) fire up a second copy of dbx and attach to the child's pid while it is sleeping. I don't know what to do to stop all processes when any one hits a breakpoint.
