ZMQ Constant Types ZMQ::SOCKET_PAIR Exclusive pair pattern ZMQ::SOCKET_PUB Publisher socket ZMQ::SOCKET_SUB Subscriber socket ZMQ::SOCKET_REQ Request socket ZMQ::SOCKET_REP Reply socket ZMQ::SOCKET_XREQ Alias for SOCKET_DEALER ZMQ::SOCKET_XREP Alias for SOCKET_ROUTER ZMQ::SOCKET_PUSH Pipeline upstream push socket ZMQ::SOCKET_PULL Pipeline downstream pull socket ZMQ::SOCKET_ROUTER Extended REP socket that can route replies to requesters ZMQ::SOCKET_DEALER Extended REQ socket that load balances to all connected peers ZMQ::SOCKET_XPUB Similar to SOCKET_PUB, except you can receive subscriptions as messages. The subscription message is 0 (unsubscribe) or 1 (subscribe) followed by the topic. ZMQ::SOCKET_XSUB Similar to SOCKET_SUB, except you can send subscriptions as messages. See SOCKET_XPUB for format. ZMQ::SOCKET_STREAM Used to send and receive TCP data from a non-ØMQ peer. Available if compiled against ZeroMQ 4.x or higher (Value: &integer;). ZMQ::SOCKOPT_HWM The high water mark for inbound and outbound messages is a hard limit on the maximum number of outstanding messages ØMQ shall queue in memory for any single peer that the specified socket is communicating with. Setting this option on a socket will only affect connections made after the option has been set. On ZeroMQ 3.x this is a wrapper for setting both SNDHWM and RCVHWM. (Value: &integer;). ZMQ::SOCKOPT_SNDHWM The ZMQ_SNDHWM option shall set the high water mark for outbound messages on the specified socket. Available if compiled against ZeroMQ 3.x or higher (Value: &integer;). ZMQ::SOCKOPT_RCVHWM The SOCKOPT_RCVHWM option shall set the high water mark for inbound messages on the specified socket. Available if compiled against ZeroMQ 3.x or higher (Value: &integer;). ZMQ::SOCKOPT_AFFINITY Set I/O thread affinity (Value: &integer;) ZMQ::SOCKOPT_IDENTITY Set socket identity (Value: &string;) ZMQ::SOCKOPT_SUBSCRIBE Establish message filter. Valid for subscriber socket (Value: &string;) ZMQ::SOCKOPT_UNSUBSCRIBE Remove message filter. Valid for subscriber socket (Value: &string;) ZMQ::SOCKOPT_RATE Set rate for multicast sockets (pgm) (Value: &integer; >= 0) ZMQ::SOCKOPT_RECOVERY_IVL Set multicast recovery interval (Value: &integer; >= 0) ZMQ::SOCKOPT_RECONNECT_IVL Set the initial reconnection interval (Value: &integer; >= 0) ZMQ::SOCKOPT_RECONNECT_IVL_MAX Set the max reconnection interval (Value: &integer; >= 0) ZMQ::SOCKOPT_MCAST_LOOP Control multicast loopback (Value: &integer; >= 0) ZMQ::SOCKOPT_SNDBUF Set kernel transmit buffer size (Value: &integer; >= 0) ZMQ::SOCKOPT_RCVBUF Set kernel receive buffer size (Value: &integer; >= 0) ZMQ::SOCKOPT_RCVMORE Receive multi-part messages (Value: &integer;) ZMQ::SOCKOPT_TYPE Get the socket type. Valid for getSockOpt (Value: &integer;) ZMQ::SOCKOPT_LINGER The linger value of the socket. Specifies how long the socket blocks trying flush messages after it has been closed (Value: &integer;) ZMQ::SOCKOPT_BACKLOG The SOCKOPT_BACKLOG option shall set the maximum length of the queue of outstanding peer connections for the specified socket; this only applies to connection-oriented transports. (Value: &integer;) ZMQ::SOCKOPT_MAXMSGSIZE Limits the maximum size of the inbound message. Value -1 means no limit. Available if compiled against ZeroMQ 3.x or higher (Value: &integer;) ZMQ::SOCKOPT_SNDTIMEO Sets the timeout for send operation on the socket. Value -1 means no limit. Available if compiled against ZeroMQ 3.x or higher (Value: &integer;) ZMQ::SOCKOPT_RCVTIMEO Sets the timeout for receive operation on the socket. Value -1 means no limit. Available if compiled against ZeroMQ 3.x or higher (Value: &integer;) ZMQ::SOCKOPT_IPV4ONLY Disable IPV6 support if 1. Available if compiled against ZeroMQ 3.x (Value: &integer;) ZMQ::SOCKOPT_LAST_ENDPOINT Retrieve the last connected endpoint - for use with * wildcard ports. Available if compiled against ZeroMQ 3.x or higher (Value: &string;) ZMQ::SOCKOPT_TCP_KEEPALIVE_IDLE Idle time for TCP keepalive. Available if compiled against ZeroMQ 3.x or higher (Value: &integer;) ZMQ::SOCKOPT_TCP_KEEPALIVE_CNT Count time for TCP keepalive. Available if compiled against ZeroMQ 3.x or higher (Value: &integer;) ZMQ::SOCKOPT_TCP_KEEPALIVE_INTVL Interval for TCP keepalive. Available if compiled against ZeroMQ 3.x or higher (Value: &integer;) ZMQ::SOCKOPT_DELAY_ATTACH_ON_CONNECT Set a CIDR string to match against incoming TCP connections. Available if compiled against ZeroMQ 3.x or higher (Value: &string;) ZMQ::SOCKOPT_TCP_ACCEPT_FILTER Set a CIDR string to match against incoming TCP connections. Available if compiled against ZeroMQ 3.x or higher (Value: &string;) ZMQ::SOCKOPT_XPUB_VERBOSE Set the XPUB to receive an application message on each instance of a subscription. Available if compiled against ZeroMQ 3.x or higher (Value: &string;) ZMQ::SOCKOPT_ROUTER_RAW Sets the raw mode on the ROUTER, when set to 1. In raw mode when using tcp:// transport the socket will read and write without ZeroMQ framing. Available if compiled against ZeroMQ 4.0 or higher (Value: &string;) ZMQ::SOCKOPT_IPV6 Enable IPV6. Available if compiled against ZeroMQ 4.0 or higher (Value: &string;) ZMQ::CTXOPT_MAX_SOCKETS The socket limit for this context. Available if compiled against ZeroMQ 3.x or higher (Value: &integer;) ZMQ::POLL_IN Poll for incoming data ZMQ::POLL_OUT Poll for outgoing data ZMQ::MODE_NOBLOCK Non-blocking operation. Deprecated, use ZMQ::MODE_DONTWAIT instead ZMQ::MODE_DONTWAIT Non-blocking operation ZMQ::MODE_SNDMORE Send multi-part message ZMQ::DEVICE_FORWARDER Forwarder device ZMQ::DEVICE_QUEUE Queue device ZMQ::DEVICE_STREAMER Streamer device ZMQ::ERR_INTERNAL ZMQ extension internal error ZMQ::ERR_EAGAIN Implies that the operation would block when ZMQ::MODE_DONTWAIT is used ZMQ::ERR_ENOTSUP The operation is not supported by the socket type ZMQ::ERR_EFSM The operation can not be executed because the socket is not in correct state ZMQ::ERR_ETERM The context has been terminated
