How to seek >2gb files with fseek?

[IGx89]

I need to make a program that uses fxxxx (fopen, ftell, fseek, fread, etc...) functions to support >2gb files. How would I do that? I see _fseeki64.c and _ftelli64.c in crt\src\, but can't figure out how to use those functions in my program (no matter what I do, I get an unresolved external symbol error). A Google search on those functions turns up virtually nothing :(.

I think you'll need to move to the Win32 API functions CreateFile, SetFilePointer, and ReadFile... You can look these up in the Docs.  onwards and upwards...

I actually finally got it working, by putting extern "C" int __cdecl _fseeki64(FILE *, __int64, int); extern "C" __int64 __cdecl _ftelli64(FILE *); in my header :D.
