When I say we should write binary data, I pretty much mean fwrite(&p, sizeof(pval), 1, fp). If you want to worry about endians and bit sizes, you have to go through the data and reverse the order of bytes on platforms which are reversed from your 'standard' platform (with endians) and pack stuff up (with platforms that have different bit sizes). Both seem plane wrong when you never really use the same data on different platforms.
