The length of the arrays in a struct utsname is unspecified; the fields are terminated by a null byte (?????? ???).
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. A bientot, Armin.
