Hi a friend of mine involved in a porting project.
He has asking me something about socket and more I am not able to answer  :-)

Thanks for your attention...

--- begin ---

[...]
that are familiar with "low-level-TCP/IP" coding.
plz help

following problem:
I don't know how to get an errorcode in case of socket-operation failed 
(send/recv)
in windows it goes like this

e.g
res = send(....);
if (res==SOCKET_ERROR)
{
err = WSAGetLastError();
if (err==....) ...;
}

but how to do this in linux/UNIX/BSD ?
what's the equivalent of WSAGetLastError ?

furthermore I need to know the errorcodes of
"wouldblock" and "connreset"
