FSCTL_GET_REPARSE_POINT IOCTL (winioctl.h)
Retrieves the reparse point data associated with the file or directory identified by the specified handle.
To perform this operation, call the DeviceIoControl function with the following parameters.
BOOL DeviceIoControl(
(HANDLE) hDevice, // handle to file or directory
FSCTL_GET_REPARSE_POINT, // dwIoControlCode
NULL, // lpInBuffer
0, // nInBufferSize
(LPVOID) lpOutBuffer, // output buffer
(DWORD) nOutBufferSize, // size of output buffer
(LPDWORD) lpBytesReturned, // number of bytes returned
(LPOVERLAPPED) lpOverlapped // OVERLAPPED structure
);
