[Qemu-commits] [COMMIT f7188bb] monitor: Setup a QDict with arguments to handlers |
Date: |

From: Luiz Capitulino <address@hidden>
With this commit monitor_handle_command() will be able to setup a
QDict with arguments to command handlers.
However, the current 'args[]' method is still being used, next
changes will port commands to get their arguments from the dictionary.
Two changes are worth noting:
1. The '/' argument type always adds the following standard keys in the
dictionary: 'count', 'format' and 'size'. This way, the argument
name used in the 'args_type' string doesn't matter
2. The optional argument type '?' doesn't need to pass the additional
'has_arg' argument, hanlders can do the same check with qdict_haskey()
