The first thing we need to know about select,poll,epoll is The mechanism of IO multiplexing. I/O multiplexing is a mechanism by which multiple descriptors can be monitored, and once a descriptor is ready (usually read-ready or write-ready), the program can be notified of the appropriate read and write operations. But select,poll,epoll are essentially synchronous I/O , because they all need to be responsib
I. About POLLFor the IO multiplexing model, the advantage is that it eliminates the wait for one IO event to be ready, instead of detecting multiple IO data at the same time, when at least one of the waiting events is ready, it will return to tell the user that the process "has data ready, quickly see which one to deal with", For the implementation of IO multiplexing, in addition to the use of the Select function, another function still supports the multiplexed IO model, which is the

Select, poll, and epoll are Io multiplexing mechanisms. The so-called I/O multiplexing mechanism means that multiple descriptors can be monitored through one mechanism. Once a descriptor is ready (generally read or write ), notify the program to perform corresponding read/write operations. However, select, poll, and epoll are essentially synchronous I/O, because they all need to read and write after the Rea
