关于ReadConsoleInput与Segmentation fault的问题！

问题相关代码，请勿粘贴截图

#include<windows.h>
HANDLE hin=GetStdHandle(STD_INPUT_HANDLE),hout=GetStdHandle(STD_OUTPUT_HANDLE);
INPUT_RECORD Buf;

//隐藏光标
void HideCursor(){
    CONSOLE_CURSOR_INFO CursorInfo;
    GetConsoleCursorInfo(hout,&CursorInfo);
    CursorInfo.bVisible = 0;
    SetConsoleCursorInfo(hout,&CursorInfo);
}
int main(){
    HideCursor();
    while(1){
        ReadConsoleInput(hin,&Buf,64,NULL);
        std::printf("x:%d y:%d",Buf.Event.MouseEvent.dwMousePosition.X,Buf.Event.MouseEvent.dwMousePosition.Y);
        Sleep(1000);
    }
}

运行结果及报错内容

Segmentation fault

我的电脑是64位系统

代码修改如下：

#include <windows.h>
#include <stdio.h>

HANDLE hin=GetStdHandle(STD_INPUT_HANDLE),hout=GetStdHandle(STD_OUTPUT_HANDLE);
INPUT_RECORD Buf;
//隐藏光标
void HideCursor(){
    CONSOLE_CURSOR_INFO CursorInfo;
    GetConsoleCursorInfo(hout,&CursorInfo);
    CursorInfo.bVisible = 0;
    SetConsoleCursorInfo(hout,&CursorInfo);
}
int main(){
    HideCursor();
    
    //用于存储读取记录
    DWORD res;
    
    COORD pos;
    while(1){
        ReadConsoleInput(hin,&Buf,1,&res); //这里最后两个参数用1和res变量
        pos = Buf.Event.MouseEvent.dwMousePosition; //这里用pos变量暂存坐标
        printf("x:%d y:%d",pos.X,pos.Y);
        Sleep(1000);
    }
}

判断一下hin是不是为空
