Parameters

Input buffer

NULL

Input buffer length

Zero.

Output buffer

Pointer to a DRV_VERSION structure.

Output buffer length

Input/output buffer length

Status block

Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful. Otherwise, Status to the appropriate error condition as a NTSTATUS code.

Remarks

DeviceIoControl Parameters

When the DeviceIoControl function is called with the IOCTL_GET_VERSION I/O control code, the caller must specify the address of a DRV_VERSION structure as the function's lpOutBuffer parameter. The kernel-mode driver fills in the structure members.

For more information, see Accessing Kernel-Mode Drivers for Still Image Devices.
