Description:
|
|
|
|
Called by any thread to make sure that the highest-priority available job is being downloaded.
|
|
It finds the highest-priority job that is in the QUEUED or RUNNING state.
|
|
If this job is different from the current download job, the current job is cancelled and
|
|
the new job is started. If no job is currently running, the new job is started.
|
|
|
|
Starting the new job requires interrupting the download thread.
|
|
|
|
At entry:
|
|
|
|
m_CurrentJob is the job being downloaded
|
|
If the downloader thread is active, then the manager's work item is in the scheduler.
|
|
Otherwise it is not.
|
|
|
|
At exit:
|
|
|
|
the best available job to download is in m_CurrentJob, or NULL if none available
|
|
If a job is available, the work item is in the task scheduler.
