Detailed Description

This class exists as an imperfect workaround to allow both "fire and forget" children and children about whose return code we actually care. (maybe we could fork and daemonize ourselves for the first case instead?)

Constructor & Destructor Documentation

FChildWaiterThread()

Member Function Documentation

Exit()

virtual void FChildWaiterThread::Exit ( void  )

inlinevirtual

Exits the runnable object.

Called in the context of the aggregating thread to perform any cleanup.

See also

Init, Run, Stop

Reimplemented from FRunnable.

Run()

virtual uint32 FChildWaiterThread::Run ( )

inlinevirtual

Runs the runnable object.

This is where all per object thread work is done. This is only called if the initialization was successful.

Returns

The exit code of the runnable object

Init, Stop, Exit

Implements FRunnable.
