检索inotify_event的全路径名 [英] Retrieve the full path name from inotify_event

问题描述

该inotify_event结构是这样的：

The inotify_event struct looks like this :

struct inotify_event {
int      wd;       /* Watch descriptor */
uint32_t mask;     /* Mask of events */
uint32_t cookie;   /* Unique cookie associating related
                      events (for rename(2)) */
uint32_t len;      /* Size of name field */
char     name[];   /* Optional null-terminated name */

};

名称部分仅存储文件名（不是文件路径）。我们如何得到来自inotify_event结构的完全限定路径或我环绕我自己的结构？

The name part stores only the file name(not the path to the file). How do we get the fully qualified path from the inotify_event struct or do I have to wrap my own struct around it ?

编辑：我等周边2秒的事件，然后处理它在一个go.I保持活动的队列中。我的问题是我是否可以从inotify_event结构得到完整的路径，我的文件只？

I wait for the events for around 2s and then process it on one go.I maintain a queue of events. My question is whether I can get the complete path to my file from the inotify_event struct only ?

每秒的事件的数目是大的。

The number of events per second is large.

推荐答案

有两种选择：结果

1. 您正在观看的文件。您已通过其更名为 inotify_add_watch ，找来一块手表描述符。如果你得到一个事件，您可以通过手表描述找出文件。结果

1. You're watching a file. You have passed its name to inotify_add_watch, and got a watch descriptor. If you get an event, you can figure out the file by the watch descriptor.
   

您正在观看的目录。同样，你已通过目录名 inotify_add_watch ，并可以找到它的名字是根据手表ID。现在 inotify_event.name 包含文件名。将两者连接起来，就大功告成了。

You're watching a directory. Again, you have passed the directory name to inotify_add_watch, and can find which name it was, based on the watch ID. Now inotify_event.name contains the file name. Concatenate the two and you're done.
