我在C中有两个函数涉及主套接字和从套接字之间的通信。主套接字使用sendSyncMessage函数向从套接字发送时间戳，而从套接字使用receiveSyncMessage接收时间戳。主套接字产生正确的输出（例如，“2023-12-07 11：07：03”），但从套接字返回错误代码10014。
主机和从机的IP地址都是127.0.0.1，端口是4455。
主设备产生正确的输出，但从设备返回错误代码10014。我怀疑recvfrom的使用方式有问题。有人能帮助我确定并解决这个问题吗？

void sendSyncMessage(SOCKET clientSocket, struct sockaddr_in client_address)
{
    SYSTEMTIME systemTime;
    char buffer[1024];

    GetLocalTime(&systemTime);

    sprintf(buffer, "SYNC:%04d-%02d-%02d %02d:%02d:%02d",  systemTime.wYear, systemTime.wMonth, systemTime.wDay,
        systemTime.wHour, systemTime.wMinute, systemTime.wSecond);

    printf("The current timestamp : %s\n", buffer);

    sendto(clientSocket, buffer, sizeof(buffer), 0, (struct sockaddr*)&client_address, sizeof(client_address));
}

void receiveSyncMessage(SOCKET server_socket)
{
    struct sockaddr_in server_address;
    int server_address_size = sizeof(server_address);
    char buffer[1024];

    int bytesReceived = recvfrom(server_socket, buffer, sizeof(buffer), 0, (struct sockaddr*)&server_address, server_address_size);
    if (bytesReceived == SOCKET_ERROR) {
    fprintf(stderr, "Receive failed: %ld\n", WSAGetLastError());
    }
    else{
        buffer[bytesReceived] = '\0';
        printf("Received Sync timestamp: %s\n", buffer);
        printf("Bytes received: %d\n", bytesReceived);
     }    
}
