Epoll is frequently utilized for handling the concurrent problem of service end.When the online number of service end is more and more, can cause be
System resource is critical, and I/O efficiency is slower and slower, at this time should just consider epoll.Epoll is that linux kernel is large quantities of to handle
Handle and the poll made improvements, are the distinctive I/O functions of Linux.Epoll is that I/O interface select/ is multiplexed under Linux
Poll enhancing version.It is realized and occupation mode has many differences with select/poll, and epoll is by one group of function come complete
Into relevant task, rather than a function.Why efficient epoll is, is because epoll puts the filec descriptor that user is concerned about
In an event table in kernel, rather than as select/poll is called every time it is required for repeating incoming file descriptor sets
Or event set.For example when an event occurs (such as reading event), epoll need not travel through the descriptor set being entirely listened,
As long as travel through those adds the descriptor set of ready queue by the asynchronous wake-up of kernel I/O event.Epoll has two kinds
Working method, LT (level triggered)：Level triggering and ET (edge-triggered)：Edging trigger.LT is
The triggering mode that select/poll is used, it is more poorly efficient；And ET is epoll high speed operation mode.
Epoll shares three functions, and when service end epoll, step is as follows：Epoll_create functions are called to exist
An event table is created in linux kernel；Then filec descriptor (monitoring socket) is added in created event table；
In major cycle, the ready filec descriptor set to be returned such as epoll_wait are called；Ready event sets are handled respectively.
