winsock2

I use NetBeans, Windows and Cygwin with g++ compiler. I'm examining Windows Sockets 2. I do everything that is written in MS manual . I have a code (mostly from this manual): #include <winsock2.h> #include <ws2tcpip.h> #include <cstdlib> #include <iostream> #pragma comment(lib, "Ws2_32.lib") int main() { WSADATA wsaData; int iResult; // Initialize Winsock iResult = WSAStartup(MAKEWORD(2,2), &wsaData); if (iResult != 0) { printf("WSAStartup failed: %d\n", iResult); return 1; } else cout << "Initialization OK."; return 0; } And I have a problem when I try to run the project: undefined reference

I am developing a RTSP Source filter in C++, and I am using WINSOCK 2.0 - blocking socket. When I create a blocking socket, I set its SO_RCVTIMEO to 3 secs like so: int ReceiveTimeout = 3000; int e = setsockopt(Socket, SOL_SOCKET, SO_RCVTIMEO, (char*)&ReceiveTimeout, sizeof(int)); My filter tries to connect to IP_ADDRESS:554 (554 is RTSP server port). If there is a server listening on that IP on the port 554, all goes well, but: If my filter creates a socket to an existing IP address , but on a random port which no one listens on, connect() waits for 3 secs and returns WSAETIMEDOUT . So after

I'm trying to add IPv6 compatibility to an already IPv4-compatible program in C, but having some problems with the compiler. Currently compiling with mingw32-gcc-4.6.2, which gives me a linking error when using the function inet_pton. I've tried making it compile for vista(as inet_pton is a vista function), but it seems like the whole function is missing from mingw. Is there any way to add it to mingw, or any other options I may have missed? Looking in my past codes - Tested in MinGW/GCC: int inet_pton(int af, const char *src, char *dst) { switch (af) { case AF_INET: return inet_pton4(src, dst

Hello i am having a problem with a socket server and client. The problem is that the messages get mixed up when i send them really fast. When i send them lets say 1 message per second everything runs good, but when i sned them 1 message per 40ms they get mixed up. here is my code for recieving: std::string* AteneaClient::readSocket () { std::string finalString = std::string(""); int size = MSG_SIZE; bool receiving = true; int timesBufferInc=0; while (receiving) { std::string temporalString; //create an empty buffer char* RCV_BUFFER = (char*) malloc (size* sizeof(char)); for(int i=0;i<size;i++)

I'm having a really hard time understanding why is this piece of code making my computer beep. I've isolated this section of code to be the one producing the occasional beep, but I don't see what's the problem with it. const int BUFFER_LENGTH = 8192; char buffer [BUFFER_LENGTH + 1]; int recvResult; do { recvResult = recv(webSocket, buffer, BUFFER_LENGTH, 0); buffer[recvResult] = '\0'; printf("%s", buffer); if (recvResult > 0) { sendResult = send(clientSocket, buffer, recvResult, 0); } }while (recvResult > 0); shutdown(webSocket, SD_SEND); To give a little bit of context, this is for a computer

For my Uni assignment I have to create a fast action paced networked game and so have chosen to use UDP as opposed to TCP. I am aware of a lot of the differences in programming both UDP and TCP and have read through most of the relevant parts of MSDN's documentation on winsock. On MSDN it states that creating a UDP socket via the connect() function should bind the socket to the address and port specified and as a result be able use the send() and recv() functions with the created socket. For my application I create a client and use connect() using the loopback address which sends a number of
