FSCTL_CSV_QUERY_DOWN_LEVEL_FILE_SYSTEM_CHARACTERISTICS IOCTL

Retrieves information about a file system for which CSVFS is a proxy.

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

BOOL DeviceIoControl(
  (HANDLE) hDevice,                                       // handle to device
  FSCTL_CSV_QUERY_DOWN_LEVEL_FILE_SYSTEM_CHARACTERISTICS, // dwIoControlCode
  NULL,                                                   // input buffer
  0,                                                      // size of input buffer
  (LPVOID) lpOutBuffer,                                   // lpOutBuffer
  (DWORD) nOutBufferSize,                                 // nOutBufferSize
  (LPDWORD) lpBytesReturned,                              // number of bytes returned
  (LPOVERLAPPED) lpOverlapped                             // OVERLAPPED structure
);
