cThread::cThread | ( | const char * | Description = NULL , |

Creates a new thread.
If Description is present, a log file entry will be made when the thread starts and stops (see SetDescription()). The Start() function must be called to actually start the thread. LowPriority can be set to true to make this thread run at a lower priority.

A derived cThread class must implement the code it wants to execute as a separate thread in this function.
If this is a loop, it must check Running() repeatedly to see whether it's time to stop.
Implemented in cIndexFileGenerator, cDirCopier, cEpgDataWriter, cTSBuffer, cDevice, cDvbTuner, cCuttingThread, cDvbPlayer, cRecordings, cEpgDataReader, cTrueColorDemo, cKbdRemote, cNonBlockingFileReader, cCiAdapter, cRemoveDeletedRecordingsThread, cDvbSubtitleConverter, cRcuRemote, cRecorder, cSectionHandler, and cLircRemote.

Cancels the thread by first setting 'running' to false, so that the Action() loop can finish in an orderly fashion and then waiting up to WaitSeconds seconds for the thread to actually end.
If the thread doesn't end by itself, it is killed. If WaitSeconds is -1, only 'running' is set to false and Cancel() returns immediately, without killing the thread.

bool cThread::Start | ( | void | ) |
Sets the description of this thread, which will be used when logging starting or stopping of the thread.
Make sure any important information is within the first 15 characters of Description, because only these may be displayed in thread listings (like 'htop', for instance). Actually starts the thread. If the thread is already running, nothing happens.
