Multi-process and 'inferior'

Multi-process and 'inferior'

[Marc Khouzam]

Hi,

With multi-process debugging, what will the 'inferior' be?

In fact, currently, when using attach/detach with gdbserver, what is 
considered the inferior?  I assume that the inferior is the process 
GDB is currently attached to, right?
 
Thanks

Marc

In what context?  Conceptually, I'd guess it all the attached
processes would be inferiors.

Yes.  It's no different than local attach/detach.

At this time, I'm thinking of "set inferior-tty"

But maybe having GDB handle many inferiors instead of the
one, would affect other commands?

Oh, many commands, I expect... Especially in the vague world of "set".
If you want to be able to specify different TTYs for each process we'd
need a new command.  The easiest thing to do would be to honor
inferior-tty for every process GDB runs (it doesn't apply when we attach).

That sounds good enough.

Thanks

Many years ago, we tried to give up using that term, "inferior".
Sounds sort of politically incorrect, though I'm glad that it 
doesn't seem to have the same 'squick factor' now as it did 
in the 1990's...
