2.2.2.11 MQMSGACKNOWLEDGEMENT

  • Article

The MQMSGACKNOWLEDGEMENT enumeration defines flags for the Message.AcknowledgementsRequested property. The values of the enumeration indicate the categories of administrative acknowledgment messages that are generated in response to successful or unsuccessful delivery outcomes. Administrative acknowledgment messages are generated to indicate the delivery outcome of a message that was originated by a client of this protocol. The MQMSGCLASS (section 2.2.2.9) enumeration specifies the types of administrative acknowledgment messages and the specific conditions in which they are produced by the message queuing system.

 typedef enum

   MQMSG_ACKNOWLEDGMENT_NONE = 0x00,

   MQMSG_ACKNOWLEDGMENT_POS_RECEIVE = 0x02,
   MQMSG_ACKNOWLEDGMENT_NEG_ARRIVAL = 0x04,
   MQMSG_ACKNOWLEDGMENT_NEG_RECEIVE = 0x08,
