x11获得窗口名的代码

具体代码：

/**
_NET_WM_NAME: 类似Window: 126
WM_NAME: XStoreName设置的值
*/
bool get_window_name(Display* dpy, Window window, char* pName)
{
#if 1
char **srname = (char **)malloc(sizeof(char *));
XFetchName(dpy, window, srname);
printf("%s-%d %s\n", __func__, __LINE__, srname[0]);
#else
    //尝试使用_NET_WM_NAME方式获取窗口的名称
    XTextProperty tp;
    Status s1 = XGetTextProperty(dpy,window,&tp,XInternAtom(dpy, 
        "WM_NAME",
        False));
    if (tp.nitems <= 0)
    {
        return false;
    }

    int count = 0;
    char **list = NULL;
    int ret = XmbTextPropertyToTextList(dpy, &tp, &list, &count);
    if ((ret == Success || ret > 0) && list != NULL)
    {
        for (int i=0; i<count; i++)
        {
             sprintf(pName, "%s", list[i]);
        }
        XFreeStringList(list);
    }
    else
    {
        sprintf(pName, "%s", tp.value);
    }
#endif
    return true;
}
