fseek equivalent for large files (>5GB) on MSVC 2002 .NET

Hi,
 Our code needs to provide access to fseek/ftell like APIs for files of arbitrary size using MSVC++ .NET 2002.
 The perfect analogues on MSVC 2005 is _fseeki64 and _ftelli64. However, these are not available in VS 2002. All we have are low level equivalents _lseeki64 and _telli64. Unfortunately, user code calls buffered I/O routines such as fgetc. Hence while using _lseeki64 we've faced too many problems and inconsistent results.
 We are looking for buffered equivalents for _fseeki64 and _ftelli64 that work on large files. User must be able to use the usual SEEK_SET, SEEK_END and SEEK_CUR consistently with this fseek implementation. Has anyone faced this problem before?

Thanks,
Raj
