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.)
EventUtil::IPPROTO_IPV6: See the socket(7) manual page. (Added in event-1.6.0.)
EventUtil::LIBEVENT_VERSION_NUMBER: Libevent' version number at the time when Event extension had been compiled with the library.

EventUtil::__construct — The abstract constructor
EventUtil::getLastSocketErrno — Returns the most recent socket error number
EventUtil::getLastSocketError — Returns the most recent socket error
EventUtil::getSocketFd — Returns numeric file descriptor of a socket, or stream
EventUtil::getSocketName — Retreives the current address to which the socket is bound
EventUtil::setSocketOption — Sets socket options
EventUtil::sslRandPoll — Generates entropy by means of OpenSSL's RAND_poll()
