Question

Using gdb, I need to run extra commands right before continue and immediately after it breaks. I thought I would make a user defined command like so:

define continue
    pre_continue
    continue
    post_continue
end

This, of course, fails in a bottomless recursive pit. Is there a way to call the built-in command directly, bypassing the user defined command?

BTW: I need the command to be named continue so that the gdb frontend I’m using will call my user defined function.

Answer 1

User-defined Command Hooks is what you are looking for:

You may define hooks, which are a special kind of user-defined
command. Whenever you run the command foo', if the user-defined
commandhook-foo’ exists, it is executed (with no arguments) before
that command.

A hook may also be defined which is run after the command you
executed. Whenever you run the command foo', if the user-defined
commandhookpost-foo’ exists, it is executed (with no arguments)
after that command. Post-execution hooks may exist simultaneously with
pre-execution hooks, for the same command.

This solution should work for you:

define hook-continue
pre_continue
end

define hookpost-continue
post_continue
end
