An application can use IOCTL_KS_READ_STREAM to read data from a pin. The application passes IOCTL_KS_READ_STREAM with the parameters described below to the KsSynchronousDeviceControl function.
The application places a pointer to an array of KSSTREAM_HEADER structures in the InBuffer parameter. Each describes a packet of data to be read. The headers can also contain the presentation time and duration.
Input Buffer Length
The InLength parameter specifies the size, in bytes, of the input buffer contents.
Stream data is returned in the buffers pointed to by the stream headers. Upon return, BytesReturned contains the number of bytes read.
Output Buffer Length
OutLength specifies the size, in bytes, of the output buffer contents.

If the request is successful, the Status member is set to STATUS_SUCCESS.
