SD_BUS_MESSAGE_SET_EXPECT_REPLY

sd_bus_message_set_expect_reply(..., 0)

sets the flag and suppresses the reply.

sd_bus_message_get_expect_reply() checks if the NO_REPLY_EXPECTED flag is set on the message m. It will return positive if it is not set, and zero if it is.

sd_bus_message_set_auto_start() sets or clears the NO_AUTO_START flag on the message m. When the flag is set the bus must not launch an owner for the destination name in response to this message. Calling

sets the flag.

sd_bus_message_get_auto_start() checks if the NO_AUTO_START flag is set on the message m. It will return positive if it is not set, and zero if it is.
