如何设置Winsock UDP套接字？

#include <winsock2.h>
#include <ws2tcpip.h>

WSADATA wsaData;
int result = WSAStartup(MAKEWORD(2, 2), &wsaData);
if (result != 0) {
    // 初始化失败，处理错误
}

SOCKET sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
if (sock == INVALID_SOCKET) {
    // 创建套接字失败，处理错误
}

sockaddr_in localAddr;
localAddr.sin_family = AF_INET;
localAddr.sin_addr.s_addr = htonl(INADDR_ANY);
localAddr.sin_port = htons(0);
int bindResult = bind(sock, (SOCKADDR*)&localAddr, sizeof(localAddr));
if (bindResult == SOCKET_ERROR) {
    // 绑定套接字失败，处理错误
}

// 发送数据
sockaddr_in remoteAddr;
remoteAddr.sin_family = AF_INET;
remoteAddr.sin_addr.s_addr = inet_addr("192.168.0.1");
remoteAddr.sin_port = htons(12345);
char sendBuffer[] = "Hello, world!";
int sendResult = sendto(sock, sendBuffer, sizeof(sendBuffer), 0, (SOCKADDR*)&remoteAddr, sizeof(remoteAddr));
if (sendResult == SOCKET_ERROR) {
    // 发送数据失败，处理错误
}

// 接收数据
char recvBuffer[1024];
sockaddr_in senderAddr;
int senderAddrSize = sizeof(senderAddr);
int recvResult = recvfrom(sock, recvBuffer, sizeof(recvBuffer), 0, (SOCKADDR*)&senderAddr, &senderAddrSize);
if (recvResult == SOCKET_ERROR) {
    // 接收数据失败，处理错误
}

closesocket(sock);
