Constructor & Destructor Documentation

InterprocessSyncNull()

isc::log::interprocess::InterprocessSyncNull::InterprocessSyncNull ( const std::string &  task_name )

inline

Constructor.

Creates a null interprocess synchronization object

Parameters

task_name

Name of the synchronization task. This has to be identical among the various processes that need to be synchronized for the same task.
