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.)

EventUtil::IPPROTO_IP

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