IOCTL_UMDF_HID_GET_FEATURE IOCTL

Description

The IOCTL_UMDF_HID_GET_FEATURE control code obtains a feature report from a HIDClass device.

Parameters

Major code

Input buffer

A UMDF-based driver calls IWDFRequest::GetInputMemory to retrieve a requester-allocated input buffer that contains the report ID of the collection.

Input buffer length

The size of the buffer obtained by calling IWDFRequest::GetInputMemory.

Output buffer

A UMDF-based driver calls IWDFRequest::GetOutputMemory to retrieve a requester-allocated output buffer. The driver uses the buffer to return a feature report.

Output buffer length

The size of the buffer that is retrieved by calling IWDFIoRequest::GetOutputMemory.

Input/output buffer

Input/output buffer length

Status block

HID minidrivers that carry out the I/O to the device must also:

Call IWDFRequest::SetInformation to set the number of bytes transferred from the device.
Call IWDFRequest::Complete with S_OK to complete the request without error. Otherwise, set the appropriate HRESULT error code.
