if you use sd_bus_reply_method_return() (or sd_bus_append()) the arguments to pass for an array is the array's size followed by the members. Hence, the following should do what you want: sd_bus_reply_method_return(m, "ay", 2, 0x01, 0x02); Lennart -- Lennart Poettering, Red Hat _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
