I'm writing simple program to communicate between smart devices and I receive 11001 when calling gethostbyaddr(). Both devices show they are connected to the same network, but from msdn document 11001 error is Host not found. No such host is known. Does anybody have any suggestion, thanks? My code is below. void InitializeSocket() {...
Hi, Is it okay to register WSACleanup through atExit function ? We have several applications that can terminate at different points in the code so we would like to avoid putting WSACleanup everywhere throughought the code. Curently we call WSAStartup / WSACleanup through DllMain since we have a dll that is used by all these applications...
I've scoured the web and have not found anything for this... Does anyone have a simple code sample of using WinSock with OpenSSL? I am looking for a simple Visual C++ 2005 or greater code sample that creates and opens a winsock connection and applies the necessary SSL settings using OpenSSL and frees all resources appropriately. ...
While reading this article, I got a doubt. I understood that while trasferring small data, Nagle algorithm is enabled by default which coalesces small packets. This results in caching some data before transmission. I believe that Winsock Kernel Buffer is the place where caching happens. Correct me if I am wrong. Does it mean that if t...
I need an app that sends an UDP packet to some network server and receives the response. The server replies to the same port number where request came from, so I first need to bind() my socket to any UDP port number. Hardcoding the UDP port number is a bad idea, as it might be used by any other application running on the same PC. Is th...
Hello, I know it is a general question but I need your recommodations about a TCP server/client application. The server is only supposed to handle one connection at a time. Server is sending live images (one frame is approx. 50K and 20 frames per second) to connected client. Actually at the startup of the server and client applicatio...
I have a dll that uses boost Asio for networking. When I link this dll to an application running on Windows 2000, a runtime exception is thrown: "The procedure entry point freeaddrinfo could not be located in the dynamic link library WS2_32.dll" Microsoft provides a workaround at http://msdn.microsoft.com/en-us/library/ms737931(VS.85)....
Most winsock tutorials on the net are preety much basic, and become useless once you got some more serious questions as to the internals of the system. MSDN is somewhat more inshightful, but tends to be preety minimalistic and sometimes ambigious. Can you recommend some good reading materials, books or articles, that really cover the su...

I'm writing an IO completion port based server (source code here) using the Windows DLL API in Python using the ctypes module. But this is a pretty direct usage of the API and this question is directed at those who have a knowledge of IOCP, not Python. As I understand the documentation for CreateIoCompletionPort, you specify your "user...
We have a Visual Basic application inside of Microsoft Access and we need to make a network connection. With VB6, there was a handy little control called WinSock that made this possible, but I can't find anything similar for the stripped down VB version that exists inside of Microsoft Access. Any ideas? Since I'm not getting any answers...
I need a client networking thread to be able to respond both to new messages to be transmitted, and the receipt of new data on the network. I wish to avoid this thread performing a polling loop, but rather to process only as needed. The scenario is as follows: A client application needs to communicate to a server via a protocol that is...
Hello! I'm programming with Winsock2. I have two network adapters in system, one for local connections (LAN), one for outer connections (PPPOE). When I perform a connect() call to connect to local address, it uses PPPOE adapter instead of LAN. I know I could tweak this using metrics, but can't I just use some hard-code to forcibly use L...
I'm currently in the middle of a project involving sockets, and I just use Linux's sys/socket.h file. Cue the port to Microsoft, and realizing that Winsock is different. I guess I have two questions. First, what're the main differences between the two implementations? Is there an easy way to "translate" them? A link to a guide would be ...
