Inotify 删除事件丢失

Question

删除同一目录下的文件时，事件丢失。

inotify监控目录：./test 删除命令：rm -rf ./test/*

文件数：20；

但是事件通知12，这是怎么回事？

int fileDescripter = inotify_init();
char buffer[BUF_LEN];
int watchDescripter = inotify_add_watch(fileDescripter, path.c_str(), IN_MODIFY | IN_CREATE | IN_DELETE);

while(true)
{
    read(fileDescripter, buffer, BUF_LEN);

    struct inotify_event *evt_inotify = (struct inotify_event*) &buffer;

string filename(evt_inotify->name);
cout << " CATCH : " << path+"/"+filename << endl;

    if(evt_inotify->len){

        if(evt_inotify->mask & IN_CREATE)
        {
            if(evt_inotify->mask & IN_ISDIR)
            {
                cout << "DIR CREATE" << endl;
            }
            else
            {
                cout << "FILE CREATE" << endl;
            }
        }
        else if(evt_inotify->mask & IN_DELETE)
        {
            if(evt_inotify->mask & IN_ISDIR)
            {
               cout << "DIR DELETE" << endl;
            }
            else
            {
               cout << "FILE DELETE" << endl;
            }

        }
        else if(evt_inotify->mask & IN_MODIFY)
        {
            if(evt_inotify->mask & IN_ISDIR)
            {

            }
            else
            {

            }
        }
    }

}\

在第12行，打印的是event notify count(12)

我解决了

inotify_init是阻塞模式，inotify_init1(IN_NONBLOCK)使用.

inotify_init读时需要锁
