By creating a new context, you start one or more input/output threads:

DEFINE context ZMQ.Context

socket()

term()

ZMQ.Socket

an object serving as an asynchronous message queue within the specified context, with the exact semantics depending on the socket type in use:

DEFINE responder ZMQ.Socket

Sockets are created by applying the socket() method to the object of ZMQ.Context type:

LET responder = context.Socket("socket_type")

bind()

unbind()

close()

connect()

getEvents()

recv()

send()

setBacklog()

setIdentity()

setLinger()

setMaxMsgSize()

getMechanism()

setReceiveBufferSize()

DEFINE context ZMQ.Poller

register()

poll()

polerr()

pollin()

pollout()

ZMQ.Msg

an object holding the message which can be sent or received via any ZMQ socket:

DEFINE msg ZMQ.Msg
