Detailed Description

Lock implementation for an ERS stream.

This class can be used to lock a particular ERS output streams to prevent output to this stream produced by concurrent threads from been mixed up. In order to employ this implementation in a stream configuration the name to be used is "lock". E.g. the following configuration will assure that the output sent to the LOG stream by concurrent threads is never mixed up:

    export DUNEDAQ_ERS_LOG="lock,stdout"
