Use the following Background Intelligent Transfer Service (BITS) interfaces to transfer files and monitor jobs within the transfer queue.
| Interface | Description |
|---|---|
| IBackgroundCopyCallback | Clients implement the IBackgroundCopyCallback interface to receive notification that a job is complete, has been modified, or is in error. |
| IBackgroundCopyCallback2 | Clients implement the IBackgroundCopyCallback2 interface to receive notification that a file has completed downloading. |
| IBackgroundCopyCallback3 | Clients implement the IBackgroundCopyCallback3 interface to receive notification that ranges of a file have completed downloading. |
| IBackgroundCopyError | Retrieves details of a job error. |
| IBackgroundCopyFile | Retrieves the local and remote file names of a file transfer request in the job and its progress. |
| IBackgroundCopyFile2 | Specifies a new remote name for the file and retrieves the list of ranges to download. |
| IBackgroundCopyFile3 | Validates the file so that peers can request its content and retrieves the name of the temporary file. |
| IBackgroundCopyFile4 | Retrieves download statistics for peers and origin servers. |
| IBackgroundCopyFile5 | Provides generic property get and set methods for BackgroundCopyFile properties. |
| IBackgroundCopyFile6 | Gets or sets generic properties of BITS file transfers. |
| IBackgroundCopyJob | Adds files to the job, sets the priority level of the job, determines the state of the job, and starts and stops the job. |
| IBackgroundCopyJob2 | Retrieves reply data from an upload job, determines the progress of the reply data transfer to the client, requests command line execution, and provides credentials for a proxy and remote server. |
| IBackgroundCopyJob3 | Downloads ranges of a file, changes the prefix of a remote file name, and maintains the owner and ACL information with the file. |
| IBackgroundCopyJob4 | Enables peer caching, restrict download time, and inspect user token characteristics. |
| IBackgroundCopyJob5 | Queries or sets several optional behaviors of a job. |
| IBackgroundCopyJobHttpOptions | Specifies client certificates for certificate-based client authentication and custom headers for HTTP requests. |
| IBackgroundCopyJobHttpOptions2 | Use this interface to retrieve and/or to override the HTTP method used for a BITS transfer. |
| IBackgroundCopyManager | Creates transfer jobs, retrieves an enumerator object of jobs in the queue, and retrieves individual jobs from the queue. |
| IBitsPeer | Gets information about a peer in the neighborhood. |
| IBitsPeerCacheAdministration | Manage the pool of peers from which you can download content. |
| IBitsPeerCacheRecord | Gets information about a file in the cache. |
| IBitsTokenOptions | Associates and manages a pair of security tokens for a Background Intelligent Transfer Service (BITS) transfer job. |
| IEnumBackgroundCopyFiles | Enumerates files in the job. |
| IEnumBackgroundCopyJobs | Enumerates jobs in the transfer queue. |
| IEnumBitsPeerCacheRecords | Enumerates the records of the cache. |
| IEnumBitsPeers | Enumerates the list of peers that BITS has discovered. |
