The MQMSGPROPS structure describes a set of message properties. It specifies the number of properties (cProp) in the set, an array containing the identifier of each property (aPropID), and an array containing the value (or placeholder for the value) of each property (aPropVar). It also provides an optional status array (aStatus) for errors associated with the property (some properties do not return a status). For detailed information about the properties that can be included in the set, see Message Properties.
