Syntax for stanzas in the trace format file

The trace format file provides rules for presentation and display of the expected data for each event ID. This allows new events to be formatted without changing the report facility.

Rules for new events are simply added to the format file. The syntax of the rules provides flexibility in the presentation of the data.

A trace format stanza can be as long as required to describe the rules for any particular event. The stanza can be continued to the next line by terminating the present line with a '\' character. The fields are described in the Files Reference.

Comments in the /etc/trcfmt file describe other format and macro possibilities and describe how a user can define additional macros.
