Parameters

Major code

Input buffer

None.

Input buffer length

None.

Output buffer

None.

Output buffer length

None.

Input/output buffer

Input/output buffer length

Status block

The Information member is set to zero. The Status member is set to STATUS_SUCCESS if the operation was successful. Otherwise, the Status member is set to the appropriate error code.

Win32 API reference (ni-winioctl-ioctl_disk_performance_off)

IOCTL_DISK_PERFORMANCE_OFF IOCTL

Description

Disables the performance counters that provide disk performance information.

To perform this operation, call the DeviceIoControl function with the following parameters.

BOOL DeviceIoControl(
  (HANDLE) hDevice,             // handle to device
  IOCTL_DISK_PERFORMANCE_OFF,   // dwIoControlCode
  NULL,                         // lpInBuffer
  0,                            // nInBufferSize
  NULL,                         // lpOutBuffer
  0,                            // nOutBufferSize
  (LPDWORD) lpBytesReturned,    // number of bytes returned
  (LPOVERLAPPED) lpOverlapped   // OVERLAPPED structure
);

Parameters

Input buffer

Input buffer length

Output buffer

Output buffer length

Input/output buffer

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.

For more information, see NTSTATUS Values.

Remarks

To enable these performance counters, use the IOCTL_DISK_PERFORMANCE control code.
