The following list describes the syntax and semantics of MQM's standard queries, used to obtain message queue information from the underlying software in order to display the MQM graphical representation. Information on these elements will be found elsewhere in the MQM Web pages.
All queries return an integer status code.
The queries have been organized into three groups, each containing all queries that share an argument structure. Returns process count and a list of all processes in the application. Returns number and list of processes that are currently blocked at any barrier. Fields can be 0 or NULL if the element doesn't apply to a particular message operation. Wild card constant can be applied to src, dest, and tag.
