Hi Folks, I would like to create and hardware watchpoint from a commands list.
retrieve the addres of a variable and create a watch.
watch *(int *) &call->stream->session->ext.settings.mode
Manualy this is working fine, but I do not know the right syntax in GDB.
I tried "watch -location call->stream->session->ext.settings.mode"
And sereval other things, is there a way to pipe the output of one
command to another one ?
watch *(int *) | printf "0x%x\n", &call->stream->session->ext.settings.mode
----------------------------------------------------------
define myhook
echo myhook \n
next
next
next
print call->stream->session->ext.settings.mode
print &call->stream->session->ext.settings.mode
printf "watch *(int *)0x%x\n", &call->stream->session->ext.settings.mode
end
break set_settings
commands
myhook
end
