I am porting some Unix code to the MS Windows platform. I have a few questions on what is the best way to incorporate the WinSock without making major modifications to the Unix IPC code. My main concern is on how to replace the BSD select. The simplest way is to replace it with WinSock's blocking select. This select internally uses PeekMessage (according to the DefaultBlockingHook in section 4.3.13). However, the winsock document strongly discourages the use of blocking call. Does this concern apply to the blocking select? I would not think so because the PeekMessage call yields control to other programs when message is available, right? Another approach is to use the WSAsyncSelect(), but this would entail too much modifications to the code. Any suggestion is greatly appreciated. Please respond to "young@telebit.com" direct or cc:, since I don't know whether my sign-up request to winsock-request is working yet. Thank you very much. dennis From slieb@morgan.com Tue Feb 15 09:36:31 1994 Received: from gateway.morgan.com by SunSITE.Unc.EDU (5.65c+IDA/FvK-1.07) with SMTP id AA03615; Tue, 15 Feb 1994 14:36:54 -0500 Received: from mercnyw1.morgan.com ([138.20.145.12]) by gateway.morgan.com with SMTP id <41433>; Tue, 15 Feb 1994 14:36:45 -0500 Received: from bwit127.morgan.com by mercnyw1.morgan.com (5.65c/IDA-sendmail/cf.hub v1.24) id AA08340; Tue, 15 Feb 1994 14:36:33 -0500 Received: by bwit127.morgan.com (5.65c/IDA-sendmail/cf.host v1.23) id AA05649; Tue, 15 Feb 1994 14:36:32 -0500 From: slieb@morgan.com (Steve Lieblich) Message-Id: <9402151436.ZM5647@is.morgan.com> Date: Tue, 15 Feb 1994 14:36:31 -0500 X-Mailer: Z-Mail (2.1.3 10feb93) To: winsock-users@sunsite.unc.edu Subject: winsock questions - How does one subscribe to this mail group? - The most recent files found in /pub/micro/pc-stuff/ms-windows/... ../winsock/winsock-users-archive and winsock-hackers-archive are read protected and thus inaccessible for anonymous ftp. Is this by design, and if so, is there an alternate site for these? If not, who should correct the permissions on these files? - I am currently developing a winsock application using Novell's Lan Workplace stack. I have designed the system to use the WSAAsyncSelect, and find under certain circumstances that my program does NOT get posted an FD_READ message when in fact the programs to which it connects are sending it data. Has anyone had similar problems with this?

I'm about to write a program which will send some stuffs to other machine using sockets. But i have a still problem with closing of sockets. If I close connection by closesocket(s), everything is OK. If second computer close connection and i receive message (lParam == 20, ....) and then I WSAAsyncSelect(s, hWnd, 0, 0); shutdown(s,2); closesocket(s); it means complete crash of WIN16 subsystem in WIN NT AS. Then I cannot make logoff neither shutdown. It is neccessary to wait about 6 minut to recover Win NT AS and to make shutdown. I cannot continue in my work without complete restart of Win NT AS. I wrote my program with BC C++ 3.1 (Trumpet Beta release #5) and I have no problem in the Windows 3.1. When I relink this program with Win NT AS winsock.lib and put it in the Win NT AS it means crash of NT. Any idea?

Are there any winsock implementations which optimize local communications (i.e., communications in which the "remote" socket is actually on the local node) by using some local IPC mechanism rather than sending the data down the networking stack, ala Unix domain sockets?
