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-?MQ 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 ?MQ 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 ZMQ_SNDHWM 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
