The Stream Programming Interface (SPI) contains functions exported by the Sync/Stream Manager to support applications that control real-time data streaming. These functions are used to create data streams, associate data objects, and for data streaming and synchronization. SPI functions also enable applications to query and install stream protocols and to query the current stream time.

The following table lists the SPI functions:

Function	Description
SpiAssociate	Associates a data object with a stream handler.
SpiCreateStream	Creates a stream instance between a source and a target stream handler.
SpiDestroyStream	Removes a stream instance from the system.
SpiDetermineSyncMaster	Determines best master stream to be used in a sync group.
SpiDisableEvent	Disables event detection for a particular event.
SpiDisableSync	Removes a group of streams.
SpiEnableEvent	Enables event detection for a particular event.
SpiEnableSync	Establishes a group of streams to synchronize the streams.
SpiEnumerateHandlers	Returns a list of the stream handler names installed in the SPI.INI file.
SpiEnumerateProtocols	Returns a list of stream protocol keys for the specified stream handler.
SpiGetHandler	Returns the handler ID for the specified stream handler.
SpiGetProtocol	Queries a stream handler for a specified stream protocol.
SpiGetTime	Queries the current stream time.
SpiInstallProtocol	Installs or removes a specified stream protocol for a stream handler.
SpiSeekStream	Seeks to a specified point in the stream object or sets the current stream time.
SpiStartStream	Starts data streaming for a single stream instance or a group of streams.
SpiSendMsg	Sends a message to a stream handler.
SpiStopStream	Stops data streaming for a single stream instance or a group of streams.
