【求助一個EPOLL的問題】

DavidHuang2010

一、驗證環(huán)境
操作系統(tǒng)：linux 2.6.36
CPU類型: MIPS


二、問題描述
當(dāng)epoll_wait函數(shù)返回后，events.events的值是正確的，但是卻發(fā)現(xiàn)events.fd始終為零。


三、源代碼
epoll.rar (1.99 KB, 下載次數(shù): 1)

[func:main line:67] listenfd = 0x3

[func:main line:97] ev.data.fd = 0x3
epoll descriptor is: 4
listen descriptor is: 3

以上打印信息為客戶端觸發(fā)事件前的服務(wù)器端調(diào)試信息；


當(dāng)然，以下打印信息為客戶端觸發(fā)事件后的服務(wù)器端調(diào)試信息；

Events Come: res=1
0: events.events = 65
0: events.fd = 0


1: events.events = 0
1: events.fd = 0


2: events.events = 0
2: events.fd = 0


3: events.events = 0
3: events.fd = 0


4: events.events = 0
4: events.fd = 0


5: events.events = 0
5: events.fd = 0


6: events.events = 0
6: events.fd = 0


7: events.events = 0
7: events.fd = 0


8: events.events = 0
8: events.fd = 0


9: events.events = 0
9: events.fd = 0


10: events.events = 0
10: events.fd = 0


11: events.events = 0
11: events.fd = 0


12: events.events = 0
12: events.fd = 0


13: events.events = 0
13: events.fd = 0


14: events.events = 0
14: events.fd = 0


15: events.events = 0
15: events.fd = 0


16: events.events = 0
16: events.fd = 0


17: events.events = 0
17: events.fd = 0


18: events.events = 0
18: events.fd = 0


19: events.events = 0
19: events.fd = 0


The 0 events descriptor is: 0
