RE: How to obtain the file length of a file larger th-an 4G in C under NT4.0?

from platform SDK doc
DWORD GetFileSize(
HANDLE hFile, // handle to file
LPDWORD lpFileSizeHigh // high-order word of file size
);
If one expects file to be larger than 4GB, pointer to DWORD variable need to
be passed as second paramter to this function.This varible contains high
word value of file size.
