IOCTL_HID_SET_FEATURE IOCTL

Description

The IOCTL_HID_SET_FEATURE request sends a feature report to a top-level collection.

For general information about HIDClass devices, see HID Collections.

Parameters

Major code

Input buffer

The Parameters.DeviceIoControl.InputBufferLength member is set to the size, in bytes, of a requester-allocated input buffer that contains a HID class feature report.

The size of the input buffer in bytes. The buffer must be large enough to hold the feature report plus one additional byte that specifies a nonzero report ID. If report ID is not used, the ID value is zero.

The Irp->AssociatedIrp.SystemBuffer member points to the input buffer that contains a feature report. If the collection includes report IDs, the requester must set the first byte of the buffer to a nonzero report ID; otherwise the requester must set the first byte to zero. The feature report is located at ((PUCHAR)ReportBuffer + 1).

Minidriver handling

Irp->UserBuffer points to a HID_XFER_PACKET structure that the HID class driver uses to input the following members:

Input buffer length

The size of the input buffer in bytes. The buffer must be large enough to hold the output report plus one additional byte that specifies a nonzero report ID. If report ID is not used, the ID value is zero.

Minidriver handling

The size of a HID_XFER_PACKET structure.

Output buffer

None.

Output buffer length

None.

Input/output buffer

Input/output buffer length

Status block

The HID class driver sets the following fields of Irp->IoStatus:

Minidriver handling

HID minidrivers that carry out the I/O to the device set the following fields of Irp->IoStatus:

HID minidrivers that call other drivers with this IOCTL to carry out the I/O, should ensure that the Information field of the status block is correct and not change the contents of the Status field.

-ReportID

Specifies the report ID for a top-level collection.

-reportBuffer

Pointer to a requester-allocated input buffer that contains a feature report.

-reportBufferLen

Specifies the size, in bytes, of the input buffer.
