Introduction
Class synopsis
Predefined Constants
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

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)

-
Send multi-part message
ZMQ::DEVICE_FORWARDER
-
Forwarder device

-
Queue device
ZMQ::DEVICE_STREAMER
-
Streamer device
ZMQ::ERR_INTERNAL

ZMQ::ERR_ENOTSUP
-
The operation is not supported by the socket type
