Libevent and multithreading

First, in the process ,libevent One of the base It's actually a while loop , When the system kernel catches the event , It will capture these events according to the priority of events , Handle with the callback function at the time of registration . How to use it with multithreading ？ I think there are two solutions .

One 、 Will monitor accept And connections connect Register with a base On , When an event triggers , Open a new thread to process the received data .

Two 、 Use 1+N Threads , One per thread base.

        1 A listening thread , He is only responsible for monitoring connections . When a new client connects , The socket Hand it over to a thread . The polling strategy can be adopted here .

        N Threads that handle client business , Each thread is only responsible for its own client time . Threads do not interfere with each other . Each thread should have a pair of pipes , Business thread listens to read time , The listening thread is when there is a new client connection , take socket Write to the queue of a business thread , And write operations to the pipeline of this thread , To trigger the pipeline multi event of this thread , Then the thread knows that a new client needs its own service , Get out of the queue socket, And listen for read Events .
