    Predefined Constants

    EventUtil::AF_INET

    IPv4 address family

    EventUtil::AF_INET6

    IPv6 address family

    EventUtil::AF_UNSPEC

    Unspecified IP address family

    EventUtil::SO_DEBUG

    Socket option. Enable socket debugging. Only allowed for processes with the CAP_NET_ADMIN capability or an effective user ID of 0 . (Added in event-1.6.0.)

    EventUtil::SO_REUSEADDR

    Socket option. Indicates that the rules used in validating addresses supplied in a bind(2) call should allow reuse of local addresses. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_KEEPALIVE

    Socket option. Enable sending of keep-alive messages on connection-oriented sockets. Expects an integer boolean flag. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_DONTROUTE

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_LINGER

    Socket option. When enabled, a close(2) or shutdown(2) will not return until all queued messages for the socket have been successfully sent or the linger timeout has been reached. Otherwise, the call returns immediately and the closing is done in the background. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_BROADCAST

    Socket option. Reports whether transmission of broadcast messages is supported. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_OOBINLINE

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_SNDBUF

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_RCVBUF

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_SNDLOWAT

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_RCVLOWAT

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_SNDTIMEO

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_RCVTIMEO

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_TYPE

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SO_ERROR

    Socket option. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SOL_SOCKET

    Socket option level. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SOL_TCP

    Socket option level. See the socket(7) manual page. (Added in event-1.6.0.)

    EventUtil::SOL_UDP

    Socket option level. See the socket(7) manual page. (Added in event-1.6.0.)
