I couldn't understand the document very well.

I would appreciate it if you could let me know if you know more about it.

For libev documents, you should refer to Head office README.
ev_async provides secure event notification for event loops in a multi-threaded environment.For example, for an event loop where one thread is ev_run(), another thread wants to notify you of the end of the loop.
Use ev_async to list the sample code for ending the event loop from another thread below.（※ Error handling is omitted.)
#include<stdio.h>
# include <unistd.h>
# include <pthread.h>
# include <ev.h>
structure ev_loop*loop;
structure ev_async shutdown_w;
static void*
thread_main(void*arg){
sleep(3);
fprintf(stderr, "ev_async_send\n");
ev_async_send(loop, & shutdown_w); // thread safe
return NULL;
}
static void
on_shutdown(struct ev_loop*loop, struct ev_async*w, int events){
fprintf(stderr, "on_shutdown\n");
ev_break(loop,EVBREAK_ALL);
}
int
main(intargc,char*argv[]){
pthread_tid;
loop = ev_default_loop(0);
ev_async_init(&shutdown_w, on_shutdown);
ev_async_start(loop, & shutdown_w);
pthread_create(&id, NULL, thread_main, NULL);
fprintf(stderr, "ev_run:start\n";
ev_run(loop,0);
fprintf(stderr, "ev_run:stop\n";
return 0;
}
