This class is available for the OPUS Blackboard API. The initial OPUS 2.0 release is described here

Constructors:

Proc_stat( )
~Proc_stat( )

Methods:

clone( )	create copy of object
name( )	get field name

Data Members:

 static const std::string IDLE;        // process is idle

 static const std::string PROCESSING;  // process is processing

 static const std::string ABSENT;      // process is absent

 static const std::string IOWAIT;      // process is in IO wait state

 static const std::string SUSPENDED;   // process is suspended

 static const std::string HALTED;      // process is halted

 static const std::string RESUMED;     // process is resuming

 static const std::string REINITED;    // process is reinitializing

Description

Proc_stat objects contain a string indicating the status of the process that is attached to that PSTAT. The following status strings are pre-defined:
