I am trying to modify some code using systemd dbus.
The method call looks like this:
res = sd_bus_call_method(bus, SERVICE_NAME, OBJECT_PATH, INTERFACE, "AddData", &error, &m, "ss", data->key, data->valyue); Now I'm trying to change that to:
res = sd_bus_call_method(bus, SERVICE_NAME, OBJECT_PATH, INTERFACE, "AddData", &error, &m, "(a(ss))", /* WHAT DO I PASS HERE? */); I can't find examples or documentation and the code is not super clear to me.
From documentation sd_bus_call_method
sd_bus_call_method() is a convenience function for initializing a bus message object and calling the corresponding D-Bus method. It combines the sd_bus_message_new_method_call(3), sd_bus_message_append(3) and sd_bus_call(3) functions into a single function call.
Details about parameters can be found on sd_bus_message_append().
res = sd_bus_call_method(bus, SERVICE_NAME, OBJECT_PATH, INTERFACE, "AddData", &error, &m, "(a(ss))", 1, /* size of array */ "hello", "world");
