Nope... Given that sockets are *not* included in Posix.1 (which is the
only posix-ism windows ever tried to support), it is not really
surprising. Sockets are completly isolated from the rest of the
libc. Error codes do not match with libc and I've just been taught by
our great WindowsGuru (hi Pascal ! :-) that there is in fact at least
3 levels of errors (errno for libc, GetLastError for win32 and
WSAGetLastError for winsock) which are completly independant...

Fun, isn't it ?

WSASetError() seems to exist indeed... But this is ugly at
best. Changing the sp.c::recv_nointr_timeout API (which is private to
sp.c anyway) should be *a lot* better...


And don't forget you'll never get a dog to walk upright
Just 'cause you've got the power, that don't mean you've got the right.
