Hello, I really strongly advise _against_ using SRFI-4 vectors for 4G files, as I have experienced serious performance issues even with vectors of a few million elements. If your C code is to be linked with your Chicken code, you can pass the pointer to your data from C to Scheme and use SRFI-4 foreign pointers to access it (see unit lolevel for details). If the C code is running as a separate process, you could try using posix-shm to create shared memory between processes and then use foreign pointers in the Chicken process.
