BG_JOB_STATE enumeration (bits.h)

Defines constants that specify the different states of a job.

Syntax

typedef enum BG_JOB_STATE {
  BG_JOB_STATE_QUEUED,
  BG_JOB_STATE_CONNECTING,
  BG_JOB_STATE_TRANSFERRING,
  BG_JOB_STATE_SUSPENDED,

  BG_JOB_STATE_ACKNOWLEDGED,
  BG_JOB_STATE_CANCELLED
} ;

Constants

 
BG_JOB_STATE_QUEUED
Specifies that the job is in the queue, and waiting to run. If a user logs off while their job is transferring, the job transitions to the queued state.
BG_JOB_STATE_CONNECTING
Specifies that BITS is trying to connect to the server. If the connection succeeds, the state of the job becomes BG_JOB_STATE_TRANSFERRING; otherwise, the state becomes BG_JOB_STATE_TRANSIENT_ERROR.
BG_JOB_STATE_TRANSFERRING
Specifies that BITS is transferring data for the job.
BG_JOB_STATE_SUSPENDED
Specifies that the job is suspended (paused). To suspend a job, call the IBackgroundCopyJob::Suspend method. BITS automatically suspends a job when it is created. The job remains suspended until you call the IBackgroundCopyJob::Resume method, IBackgroundCopyJob::Complete method, or IBackgroundCopyJob::Cancel method.
BG_JOB_STATE_ERROR
Specifies that a nonrecoverable error occurred (the service is unable to transfer the file). If the error—such as an access-denied error—can be corrected, then call the
IBackgroundCopyJob::Resume method after the error is fixed. However, if the error cannot be corrected, then call the
IBackgroundCopyJob::Cancel method to cancel the job, or call the
IBackgroundCopyJob::Complete method to accept the portion of a download job that transferred successfully.
BG_JOB_STATE_TRANSIENT_ERROR
Specifies that a recoverable error occurred. BITS will retry jobs in the transient error state based on the retry interval you specify (see IBackgroundCopyJob::SetMinimumRetryDelay method). The state of the job changes to BG_JOB_STATE_ERROR if the job fails to make progress (see IBackgroundCopyJob::SetNoProgressTimeout method).

BITS does not retry the job if a network disconnect or a disk lock error occurred (for example, chkdsk is running), or the MaxInternetBandwidth Group Policy is zero.
BG_JOB_STATE_TRANSFERRED
Specifies that your job was successfully processed. You must call the
IBackgroundCopyJob::Complete method to acknowledge completion of the job, and to make the files available to the client.
BG_JOB_STATE_ACKNOWLEDGED
Specifies that you called the IBackgroundCopyJob::Complete method to acknowledge that your job completed successfully.
BG_JOB_STATE_CANCELLED
Specifies that you called the
IBackgroundCopyJob::Cancel method to cancel the job (that is, to remove the job from the transfer queue).
