EventUtil::AF_INET

IPv4地址系列

EventUtil::AF_INET6

IPv6地址系列

EventUtil::AF_UNSPEC

Unspecified IP address family

EventUtil::SO_DEBUG

套接字选项。启用套接字调试。只允许具有CAP_NET_ADMIN功能或有效用户标识的进程0。（在event-1.6.0中添加）

EventUtil::SO_REUSEADDR

套接字选项。指示用于验证bind（2）调用中提供的地址的规则应允许重用本地地址。请参阅socket（7）手册页。（在event-1.6.0中添加）

EventUtil::SO_KEEPALIVE

套接字选项。启用在面向连接的套接字上发送保持活动消息。期望一个整数布尔标志。请参阅socket（7）手册页。（在event-1.6.0中添加）

EventUtil::SO_DONTROUTE
