NAME
     tracem - STREAMS activity trace module

DESCRIPTION
     tracem reports on messages passing through active Streams.  You can
     insert instances of tracem at any point or points in one or more Streams,
     those instances then send copies of messages passing through them to
     another instance of tracem designated as a reporting module.

     trconf(1) inserts or removes tracing instances of tracem on a Stream.  It
     also lists open Streams and the modules on them, and configures tracem
     modules to report on specific kinds of messages.  trmon(1) opens a Stream
     to /dev/nuls, pushes a reporting instance of tracem onto that Stream,
     then prints (on standard output) messages sent to the reporting instance
     by tracing instance(s).

FILES
