This is somewhat off topic so feel free to respond privately. We want to add LFS to our package. I currently do not know what this involves: I know there's the defines: -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE but I'm not sure how portable that is. Our package also gets built on VMS and Windows (using MSVC) so I don't know how portable that is. What I'm looking for is some example code that supports LFS, and that is also built in multiple environments that includes Windows using MSCV. Can anyone point me to some example source code?
