ИМЯ

       epoll_event, epoll_data, epoll_data_t - epoll event

БИБЛИОТЕКА

       Standard C library (libc)

СИНТАКСИС

       #include <sys/epoll.h>

       struct epoll_event {
           uint32_t      events;  /* Epoll events */
           epoll_data_t  data;    /* User data variable */
       };

       union epoll_data {
           void     *ptr;
           int       fd;
           uint32_t  u32;
           uint64_t  u64;
       };

       typedef union epoll_data  epoll_data_t;

ОПИСАНИЕ

       The epoll_event structure specifies data that the kernel should
       save and return when the corresponding file descriptor becomes
       ready.

ВЕРСИИ

   C library/kernel differences
       The Linux kernel headers also provide this type, with a slightly
       different definition:

           #include <linux/eventpoll.h>

           struct epoll_event {
               __poll_t  events;
               __u64     data;
           };

СТАНДАРТЫ

       Linux.
