1. Establish the connection PGconn *pg_conn = PQconnect("info"); // error check if (PQstatus(pg_conn) != CONNECTION_OK) throw "invalid connection"; 2. Grab the socket file descriptor int socket_fd = PQsocket(pg_conn); // error check if (socket_fd < 0) throw "invalid socket"; 3. Set the timeout // 5 second timeout struct timeval timeout = { 5, 0 }; // recv timeout int setopt_result_1 = setsockopt( socket_fd, SOL_SOCKET, SO_RCVTIMEO, (char *)&timeout, sizeof(timeout) ); // send timeout int seto...
