What is New in This Release
Following features are introduced in this version of HP WDB
• Enhanced thread debugging support
The thread debugging enhancement is meant for developers of POSIX multithreaded applications and provides extended
information on the state of following pthread primitives:
— threads
— mutexes
— read-write locks
— condition variables
The following new commands are supported:
— set thread-check on/off
The set thread-check on/off command can be used to enable or disable extended thread debugging
functionality. The set thread-check on/off command must be run prior to debugging the application under
HP WDB, to force the underlying runtime system to start collection of information on pthread primitives. The set
thread check feature is off by default.
— info thread [thread-id]
