- Subject: [patch/doc] Tweak "info inferiors" output.
Here's a tiny piece I'm cutting out of the pending multi-exec patch.
(Tromey, we talked a bit about this bit at the end of
http://sourceware.org/ml/gdb-patches/2009-06/msg00668.html)
This tweaks the "info inferiors" output to align columns left, removes
the "Cur" header, and makes the command query the target how to
print a process id (or better, the inferior's target side ID, there
may be no concept of processes on the other end at all).
----------------------------------------------------------
Native:
Before After
(gdb) info inferiors (gdb) info inferiors
Cur Id PID Id Target ID
* 1 3099 * 1 process 3099
----------------------------------------------------------
Remote:
Before After
(gdb) info inferiors (gdb) info inferiors
Cur Id PID Id Target ID
* 1 42000 * 1 Remote target
(gdb)
(42000 is the magic pid that is an internal detail. The user
should never see it.)
----------------------------------------------------------
More columns will be added later when multi-executable support goes in.
Comments? Eli, documentation bits ok?

* inferior.c (print_inferior): Align columns left. Remove header
for the the "current" column. Print if there's no selected
inferior.

* gdb.texinfo (Debugging Multiple Inferiors): Add "info inferiors"
small example.
