帮助：达到的最大客户端数 – 分段错误

我想模拟许多重要的新闻事件.我通过使用XTestFakeKeyEvent找到了一个解决方案,但是当我模拟超过210次时,我的程序提出了“达到的最大客户端数”分段错误.我不知道如何解决这个问题.

我的代码在这里：

#include dio.h>

#define PRESS_UP    0
#define PRESS_DOWN  1
#define PRESS_LEFT  2
#define PRESS_RIGHT 3
#define PRESS_ENTER 4
#define PRESS_ESC   5
#define PRESS_HOME  6

 display *display;
 unsigned int keycode;

 int press(int key){
    display = XOpendisplay(NULL);

    if(key == PRESS_UP)
        keycode = XKeysymToKeycode(display,XK_Up);
    else if(key == PRESS_DOWN)
        keycode = XKeysymToKeycode(display,XK_Down);
    else if(key == PRESS_LEFT)
        keycode = XKeysymToKeycode(display,XK_Left);
    else if(key == PRESS_RIGHT)
        keycode = XKeysymToKeycode(display,XK_Right);
    else if(key == PRESS_ENTER)
        keycode = XKeysymToKeycode(display,XK_Return);
    else if(key == PRESS_ESC)
        keycode = XKeysymToKeycode(display,XK_Escape);
    else if(key == PRESS_HOME)
        keycode = XKeysymToKeycode(display,XK_Home);

    XTestFakeKeyEvent(display,keycode,True,0);
    XTestFakeKeyEvent(display,False,0);
    XFlush(display);
    return 0;
}

int main(int argc,char *argv[]){
    int count = 0;
    while (count < 500){
        press(PRESS_UP);
        printf("count =%d\n",count);
        count ++;
    }
}

输出：

$gcc -lXtst -lX11 Util_KeyPressSimulator.c 
$./a.out 
count =0
^[[Acount =1
^[[Acount =2
...
^[[Acount =208
^[[Acount =209
^[[Acount =210
^[[AMaximum number of clients reachedSegmentation fault

有人请帮忙,谢谢.

最佳答案

你在每次迭代时都在进行XOpendisplay而没有匹配的XClosedisplay.考虑打开显示一次,在main()中,在循环外部,并在退出之前关闭它.
