After you obtain the handle to a bytes message from MQCreateBytesMessage , you can use this handle to define its body with the MQSetBytesMessageBytes() function, to set its application-defined properties with the MQSetMessageProperties() function, and to set certain message headers with the MQSetMessageHeaders() function.
