There appears to be no portable interface that implements out_le32() and in_le32()?iowrite32() and ioread32()?
Do they always use little endian, as these *_le32 helpers do? I though they use host byte order.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
