call(Destination::dbus_name(), Path::dbus_name(), Interface::dbus_name(), Member::dbus_name() | dbus_method()) -> dbus_message()
Equivalent to call(Destination, Path, Interface, Member, []).
call(Destination::dbus_name(), Path::dbus_name(), Interface::dbus_name(), Member::dbus_name() | dbus_method(), Opts::[dbus_option()]) -> dbus_message()
Build a method call message
error(Orig::dbus_message(), ErrName::binary(), ErrText::binary()) -> dbus_message()
Build an error message
find_field(Code::integer(), Dbus_message::dbus_header() | dbus_message()) -> dbus_variant() | undefined
Find a specific field of a message
Returns undefined if not found
get_field(Code::integer(), Header::#dbus_header{}) -> dbus_variant()
throws {no_such_field, integer()}
Get a specific field of a message.
Throws error if not found.
get_field_value(Code::integer(), Header::dbus_header()) -> term()
throws {no_such_field, integer()}

Throws error if not found.
get_serial(Dbus_message::dbus_message()) -> integer()
Get serial number from message
introspect(Service::dbus_name(), Path::dbus_name()) -> dbus_message()
Build Introspect method call message
is_error(Msg::dbus_message(), ErrName::dbus_name()) -> boolean()
Check message is an error and of the given type
match(HeaderMatches::[{integer(), dbus_name() | '_'}], Dbus_message::dbus_message()) -> boolean()
Check message headers matches some values.
'_' means the header exists with any value
