Detailed Description

Provides information about processes that have open files in a given path or subdirectory of path.

When start() is invoked it starts to collect information about processes that have any files open in path or a subdirectory of path. When it is done the KJob::result signal is emitted and the result can be retrieved with the processInfoList function.

On Unix like systems the lsof utility is used to get the list of processes. On Windows the listing always fails with error code NotSupported.

start()

void KListOpenFilesJob::start ( )

overridevirtual

Starts the job asynchronously.

When the job is finished, result() is emitted.

Warning: Never implement any synchronous workload in this method. This method should just trigger the job startup, not do any work itself. It is expected to be non-blocking.

This is the method all subclasses need to implement. It should setup and trigger the workload of the job. It should not do any work itself. This includes all signals and terminating the job, e.g. by emitResult(). The workload, which could be another method of the subclass, is to be triggered using the event loop, e.g. by code like:

void ExampleJob::start()
{
 QTimer::singleShot(0, this, &ExampleJob::doWork);
}

Implements KJob.
