RE: {simple} sockets socket.Receive question

[=?Utf-8?B?UmFqbmk=?=]

Dear Sir/Mam,

I have written a server code using the Windows Socket API's. Wherein I have
created the socket and bound it to a particular IP address and port number.
Later I have made the socket in non-blocking mode by using the proper socket
option ( i.e. SO_RCVTIMEO). After which with the use of recv() I am trying to
get into the receive mode. Here as the receive time out is being used the
socket should come out of the block mode after the time out value. But this
is not happening here, instead the socket is always in the blocking mode.

I am facing this kind of an issue only on few of the VISTA systems. Whereas
on few other VISTA systems it is working fine (means we are ableto switch
between block and non-block modes).
But there is no problem on any of the XP systems.

Could you please provide me with information related to this and help in
deriving a proper conclusion.

Thanks in advance,
Rajni

Does this function block? What happens if the client only sends 3 bytes? What if the client sends 5 bytes or 5000 bytes?

1. You only need to post the question once.

2. Your question appears to have nothing to do with .NET or C#. Rather
than hijacking a previous thread in this newsgroup that _was_ related to
..NET, you may prefer to post your question in one of the Winsock
newsgroups (i.e alt.winsock.pro gramming or
comp.os.ms-windows.program mer.tools.winso ck).

3. The SO_RCVTIMEO socket option controls the timeout for receives, not
the blocking state of the socket. If you want to set the socket to
non-blocking, use ioctlsocket() or WSAIoctl() with the FIONBIO option.
