SpiStartStream - Parameters

hstream (HSTREAM) - input

The stream that is to perform the specified action.

ulFlags (ULONG) - input

Contains none or some of the following flags:

SPI_START_STREAM

Start master stream only. This is the default setting.
SPI_START_SLAVES
Start master stream and any slave streams in the same sync group. If this flag is set, the hstream must be the stream handle of a master stream.
SPI_START_PREROLL
Preroll the stream; that is, fill all the stream buffers with data. Once this is done, the stream is in a prerolled state, which enables the stream to be started more quickly. This is an asynchronous function.

rc (ULONG) - returns

Return codes indicating success or the type of failure:

NO_ERROR

Success.
ERROR_INVALID_FUNCTION
Invalid function requested.
ERROR_INVALID_STREAM
Invalid stream handle.
ERROR_INVALID_FLAG
The flag passed is invalid.
ERROR_STREAM_NOTMASTER
Start stream with SPI_START_SLAVES flag was specified, but the stream handle passed was not a synchronization master stream.
ERROR_START_STREAM
There was an error starting the stream.
ERROR_DATA_ITEM_NOT_SPECIFIED
The data object was not specified.
ERROR_DEVICE_NOT_FOUND
The device was not found.
FAILURE
Stream handler-specific error return code.
