NAME

POEx::ZMQ3::Context - A ZMQ context singleton

SYNOPSIS

  my $zsock = zmq_socket( 
    # ->new() returns a (lazily built) singleton:
    POEx::ZMQ3::Context->new, 
    'REQ' 
  );
  # ... if you fork later:
  POEx::ZMQ3::Context->reset;

DESCRIPTION

A ZeroMQ context should be shared amongst pieces of a single process.

This is the singleton used internally by POEx::ZMQ3 bits; you can use it to retrieve the current context object if you are adding independently-managed ZMQ::LibZMQ3 sockets to the currently-running process.

Forked children should call POEx::ZMQ3::Context->reset before issuing new socket operations.

Calling POEx::ZMQ::Context->term will force a context termination. This may block (and is rarely needed); see the man page for zmq_ctx_destroy.

METHODS

new

Retrieves the ZMQ::LibZMQ3 context object for the current interpreter.

The object is a singleton; if it doesn't exist when new is called, it will be created.

reset

Clears (but does not forcibly terminate, see "term") the current context object.

Should be called in forked children to gain a fresh context object on the next call to "new".

term

Force a context termination; calls "reset" before issuing a zmq_ctx_destroy(3).
