[systemd-devel] sd-bus read message with ConnMan

[Salman Ahmed]

Some issue with formatting.I copy message again here
Hello,

I am trying to communicate with connman using sdbus from my application.
Basically I want to replicate the following cmd line procedure to get
values for "object path" and string "Host"
I do
dbus-send --system              --dest=net.connman.vpn   --type=method_call
           --print-reply                 /
 net.connman.vpn.Manager.GetConnections

and I get
   array [
      struct {
    ==>     object path "/net/connman/vpn/connection
/uk_london_privateinternetaccess_com_privateinternetaccess_com"
         array [
            dict entry(
               string "State"
               variant                   string "idle"
            )
            dict entry(
               string "Type"
               variant                   string "openvpn"
            )
            dict entry(
               string "Name"
               variant                   string "PIA VPN"
            )
            dict entry(
               string "Host"
     -==>          variant                   string "
uk-london.privateinternetaccess.com"
            )
            dict entry(
               string "Index"
               variant                   int32 0
            )
            dict entry(
               string "Domain"
               variant                   string "privateinternetaccess.com"
            )
            dict entry(
               string "Immutable"
               variant                   boolean true
            )
            dict entry(
               string "Nameservers"
               variant                   array [
                  ]
            )
            dict entry(
               string "UserRoutes"
               variant                   array [
                  ]
            )
            dict entry(
               string "ServerRoutes"
               variant                   array [
                  ]
            )
         ]
      }
   ]


In my application I am doing
       r = sd_bus_call_method( bus,
                                           "net.connman.vpn",
                                           "/",
                                           "net.connman.vpn.Manager",
                                           "GetConnections",
                                           &error,
                                           &m,  NULL, NULL);

Which succeeds.
Afterwards I want to do  sd_bus_message_read(m, "a(oa{sv})") but I have no
idea what kind of arguments should I pass in what order to get object path
and host string. I think I got the a(oa{sv}) part right?

Any help would be much appreciated
