What tools or technologies have you used for organizing network interaction?

Tools and technologies commonly used for network interaction in C/C++ include:

• Sockets — a fundamental mechanism for data exchange over a network. POSIX sockets are used in Unix-like systems, while Winsock is used in Windows.
• High-level libraries — such as Boost.Asio, which simplifies working with asynchronous I/O and network protocols.
• Data transfer protocols — TCP for reliable transmission, UDP for faster but less reliable transmission.
• RPC (Remote Procedure Call) — for invoking functions on remote machines.

Example of creating a TCP socket in C++ (simplified):

#include <sys/socket.h>
#include <netinet/in.h>
#include <unistd.h>

int sock = socket(AF_INET, SOCK_STREAM, 0);
struct sockaddr_in addr{};
addr.sin_family = AF_INET;
addr.sin_port = htons(8080);
addr.sin_addr.s_addr = INADDR_ANY;
bind(sock, (struct sockaddr*)&addr, sizeof(addr));
listen(sock, 5);
int client_sock = accept(sock, nullptr, nullptr);
// Data exchange through client_sock
close(client_sock);
close(sock);
