Thanks, Charles.

Hm, in other words, I may as well start working on porting the
socket code I am working on to Plan 9, rather than make adjustments
for the missing error codes (EWOULDBLOCK and ECONNRESET).

That may make the next question redundant: many socket functions
are prototyped in APE with "int *len" as their last argument.
These days, in NetBSD these use soclen_t which is normally a uint,
but I think provision has been made for an int in some special
instances (I think it's a platform issue).

Does anyone know if the POSIX spec has changed to use "uint *len"
instead of "int *len" in the recent past (since the APE modules
were written)?  Or "socklen *len" or "size_t *len" as I have seen
all of these on occasion?
