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.

Major code


Input buffer

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.

Input buffer length

The InLength parameter should specify the size, in bytes, of the input buffer contents.

Output buffer

Kernel streaming provides the number of bytes written in the BytesReturned parameter.

Status block

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


Requirement Value
