Module metadata 

Source
Expand description

Typed MQMD fields and message properties: selectable columns appended after the payload.

Identifiers stay binary (24-byte MsgId, CorrelId, GroupId), numeric fields keep their MQI units and sentinels (Expiry in tenths of a second, -1 unlimited), and character fields are trimmed of MQ’s space padding. UserIdentifier and PutApplName are the received context as the queue manager recorded it.

Structs§
