Using ctypes in python can convert C struct to python object. But if C++ struct like this (maybe using socket to transfer C++ struct to python): struct Struct { int a; vector<int> b; } I’m wondering how to convert C++ struct bytes with variable vector to python object. Thanks Source: Windows Que..

I’m writing a socket c++ lib for TCP. I’m compiling with GCC for x86_64-w64-mingw32.7.3.0 on windows 10. When I try to build a socket I fail. listenSocket = socket(AF_INET, SOCK_STREAM, 0); if (listenSocket < 0) { std::cout << "ERROR: OPEN SOCKET" << listenSocket << std::endl; close(listenSocket); return; } Getting the error. ERROR: OPEN SOCKET-1 Seem ..
Hoping someone can help out with this. Recently changed a program which acts as a TCP Server to help share the traffic on a serial port connected to a device. Multiple clients connect and should have access to the Serial Port and act simultaneously. Application is built using C++ Builder. Using TIdTCPServer component in the ..
I want to establish a socket connection in one method and use this connection in another method of a class. While in the first method (where I establish the connection) I can read and write from and to the socket as much as I want, in the second method I always get a Bad file ..
I’m trying too make my own sockets library in c/c++ as a final project. I’ve been looking online for information to do so. I found out that I’ll need to use pipes and processes… But didn’t really found the way how to make the computer communicate with other computer using this pipes.. I’d be happy ..
I’m currently working on a program where I’m designing my own protocol to send over UDP. The format is as follows: packet -packet type -payload where the payload has a specific format based on the packet type. Two examples of packet types are status_req and status_res: status_req -id status_res -id -status_1 -status_2 Does anyone have ..
I am building simple socket program. This program connects to different servers several times. And I found interesting behavior of Windows socket. My computer has 2 independent NICs – different network. When my program connects to server for the first time, it uses NIC 1. And after a few connect and close operation, it uses ..
I am trying to create a remote desktop application and I have a pretty good idea on how I’ll capture the screen, encode it to h.264 or HEVC and then write it to a file. In my case though, I want to have this encoded stream sent over UDP, but without the in-built streaming method ..
src.cpp #include <iostream> #include <cstring> #include <sys/types.h> #include <sys/socket.h> #include <netdb.h> int main(){ struct addrinfo hints, *servinfo; memset(&hints, 0, sizeof hints); hints.ai_family = AF_UNSPEC; hints.ai_socktype = SOCK_STREAM; hints.ai_flags = AI_PASSIVE; getaddrinfo(NULL, "1560", &hints, &servinfo); freeaddrinfo(&hints); } I used gdb to find out where the error occurs and it occurs at the memset but when I ..
I’ve been gleaning information about the NETLINK socket which allows us to listen to what is happen in socket land. It seems to very partially work, but I’m wondering whether I missed something. I’m using C++, although of course all the NETLINK is pure C, so here we have mainly C headers. The following code ..
