An application can use IOCTL_KS_WRITE_STREAM to write data to a pin. The application passes IOCTL_KS_WRITE_STREAM with the parameters described below to the KsSynchronousDeviceControl function.
A client provides a pointer to an array of KSSTREAM_HEADER structures in InBuffer. The stream data to write is contained in the buffers pointed to by the stream headers. The headers can also contain presentation time and duration.
The InLength parameter should specify the size, in bytes, of the input buffer contents.
Kernel streaming provides the number of bytes written in the BytesReturned parameter.
If the request is successful, the Status member is set to STATUS_SUCCESS.
