As the commenters have already explained, whether you can open a file of more than 2GB depends on the OS and C library, not on the compiler on
sizeof(long). If your OS supports such files, you should be able tofopenthem, although you may have to set a flag (#define _FILE_OFFSET_BITS 64for Linux).Then,
fseekindeed cannot seek to positions farther away thanLONG_MAXin a single call. You can either callfseekseveral times in a loop, which can be cumbersome, or check if your platform hasfseekowhich takes an offset argument of typeoff_t. That type should be big enough to capture the size of any (regular) file on your system if you set the right options.fseekois available on newer Linux and all POSIX-2001-compliant OSs.
