10.2.5.2.4 Userlog Maintains Thread-specific Information

For each thread in each application, userlog(3c) records the following identifying information:

process_ID.thread_ID.context_ID

Placeholders are printed in the thread_ID and context_ID fields of entries for non-threaded platforms and single-contexted applications.

The TM_MIB(5) supports this functionality in the TA_THREADID and TA_CONTEXTID fields in the T_ULOG class.
