I'm completely confused.

It means that the structure looks like this in lltype notation:

      Struct('utsname', ('text1', FixedSizeArray(Char, 10)),

                        ('text2', FixedSizeArray(Char, 20)),

                        ...)

where, annoyingly, the numbers '10' and '20' are platform-dependent and

must be obtained by trying to compile snippets of C code using sizeof()

and offsetof().

Or are you confused about the bit saying that the fields are

zero-terminated?  It just means that in the array, characters 0 to N-1

are non-null, charater N is null, and the rest of the characters are

undefined.
