In GDB, how do I execute a command automatically when program stops? (like display)

Question

I want some commands to be automatically executed each time the program stops, just like what display does with x. How do I do that?

Okay I found it for myself. I post it here just in case someone else's gonna need it. [CR] define hook-stop [CR] ...commands to be executed when execution stops [CR] end [CR] ' See [this page](http://sourceware.org/gdb/current/onlinedocs/gdb/Hooks.html#Hooks) of the GDB manual for more details — neuron, Sep 20 '11 at 06:55

Here's the easy way I found out:

define hook-stop
  ...commands to be executed when execution stops
end

Another "new" way to do it is with the Python Event interface:

 def stop_handler (event):
     print "event type: stop"

 gdb.events.stop.connect (stop_handler)

which will trigger the stop_handler function each the the inferior stops.

There are two other similar events type:

events.cont
events.exited

respectively triggered when the inferior is continued or exists.
