Hi, all.
Yesterday I observed different sizeof() of a union in a library function
and in the main program. The reason seems to be a forgotten #include
in a library source.
union U
{
struct
{
// sizeof = 100
struct NeverDefined nf; // Unknown, d
- "NeverDefined" doesn't mean "declared and
defined elsewhere (or not)" but "not declared .and. not defined".
No doubt this should be a fatal error, but 8c accepts.
What's my mistake ?
adriano
sion of structs by a
final struct field
but this, in my opinion, would imply portability problems and in
general more error
prone code.
I prefer to have only the tricky but standard "char x[0]" tails.
Your patch will be included in the next distribution CD ?
adriano
How can I implement channel selection and secure timeouts
without using APE ?
Re-write some pieces is not a problem, I prefer a "pure" 8c implementation.
adriano

Hi, all
I boot diskless (very obsolete PC) embedding the nvram data in the kernel.
Basically I implemented a fake-nram driver and declare it in the plan9.ini

If such a solution could be useful for the community I would be happy

t remember what D.Gries and others said about and I don't know the

IMHO 8c is better than gcc even if sometimes it wrongly complains about

If the goal is to manage two separate networks, one local and the other
