UDB在同一台机器上进行对等

Question

我想确保我理解这个概念 我们有example.exe，我们将在同一台计算机上运行它5次或更多次

example.exe将创建一个pear（具有发送和接收套接字） 发送套接字在固定端口上发送，接收套接字在同一端口上接收

我的问题是运行example.exe 5次 将在相同的＆＃34;机器＆＃34;上创建5个对等体。使用相同的固定端口！怎么样的！ 我尝试了代码，它正在机器上工作，这意味着相同的IP地址！

这里有一些代码

接收套接字

sockaddr_in RecvAddr;
RecvAddr.sin_family = AF_INET;
RecvAddr.sin_port = htons(PORT);
RecvAddr.sin_addr.s_addr = htonl(INADDR_ANY);

cout << RecvAddr.sin_addr.s_addr << endl;


int broadcastValue = 1;
if (setsockopt(receivingSocket, SOL_SOCKET, SO_REUSEADDR, (char*)&broadcastValue, sizeof(broadcastValue)) == SOCKET_ERROR)
    exit(EXIT_FAILURE);

int iResult = 0;
iResult = bind(receivingSocket, (SOCKADDR *)& RecvAddr, sizeof (RecvAddr));
if (iResult != 0) {
    exit(EXIT_FAILURE);

发送套接字

sockaddr_in destinationAddress;
destinationAddress.sin_family = AF_INET;
destinationAddress.sin_addr.s_addr = INADDR_BROADCAST;
destinationAddress.sin_port = htons((unsigned short)PORT);

if (sendto(sendingSocket, message.c_str(), message.length(), 0, (struct sockaddr*) &destinationAddress, sizeof(destinationAddress)) == SOCKET_ERROR)
{

    exit(EXIT_FAILURE);
}
