Struct EpollEvent

Source
#[repr(C)]
pub struct EpollEvent { pub events: EpollEventType, pub data: u64, }
Expand description

表示 epoll 事件的结构体(对应 Linux 的 struct epoll_event

MUSL: https://github.com/bminor/musl/blob/c47ad25ea3b484e10326f933e927c0bc8cded3da/include/sys/epoll.h#L49 TODO: 根据 data 的类型,可能需要使用不同的结构体来表示不同的事件, 对应 C 语言的 union NOTE: 在 x86_64 架构会添加 __attribute__ ((__packed__)),以确保结构体的内存对齐

Fields§

§events: EpollEventType

事件类型(如可读、可写等,使用 EpollEventType 表示)

§data: u64

用户数据(如 fd 或标识符),epoll 不做解释
