Trace-route message MQEPH (Embedded PCF header)

The MQEPH structure contains a description of both the PCF information that accompanies the message data of a trace-route message and the application message data which follows it. For a full description of the MQEPH structure, including a description of the elementary datatype of each parameter, see MQEPH - Embedded PCF header.

An MQEPH structure is used only if additional user message data follows the TraceRoute PCF group.
