The application places a pointer to a structure of type KSEVENTDATA in the InBuffer parameter. This is the location of the original KSEVENTDATA structure that the application instantiated at the enabling of the event. To disable all active events, a client specifies a NULL pointer and length of zero in the InBuffer and InLength parameters.
Input buffer length
Length of KSEVENTDATA.
Output buffer
None.
Output buffer length

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