VHF_CONFIG_INIT function

Description

Use the VHF_CONFIG_INIT function to initialize the required members of the VHF_CONFIG structure allocated by the HID source driver.

Syntax

FORCEINLINE
VOID
VHF_CONFIG_INIT(
    _Out_
        PVHF_CONFIG     Config,
#ifdef _KERNEL_MODE
    _In_
        PDEVICE_OBJECT  DeviceObject,
#else
    _In_
        HANDLE          FileHandle,
#endif
    _In_
        USHORT          ReportDescriptorLength,
    _In_reads_bytes_(ReportDescriptorLength)
        PUCHAR          ReportDescriptor
    )

Parameters

Config [out]

A pointer to the VHF_CONFIG structure to initialize.

DeviceObject [in]

A pointer to the DEVICE_OBJECT structure for the HID source driver. Get that pointer by calling WdfDeviceWdmGetDeviceObject and passing the WDFDEVICE handle that the driver received in the WdfDeviceCreate call.

A user-mode driver would instead provide a FileHandle. For more info, see VHF_CONFIG.

ReportDescriptorLength [in]

The length of the HID Report Descriptor contained in a buffer pointer by ReportDescriptor.

ReportDescriptor

A pointer to a HID source driver-allocated buffer that contains the HID Report Descriptor.
