Hello!

For some reason mmap(...) call with offset other then 0 fails with invalid
argument error.

The code looks like:
  msg->msg_body = (char *)mmap(NULL, (size_t)mlen, PROT_READ, 0,mfd,
            (off_t)mofft)) == (char *)-1);

You can reproduce it by running cmp with skip arguments (cmp file1 file2 10 10).
Any ideas?

Best regards.
