NAME

|
----
|
|
zmq_vmci - 0MQ transport over virtual machine communicatios interface (VMCI) sockets
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
The VMCI transport passes messages between VMware virtual machines running on the same host,
|
|
between virtual machine and the host and within virtual machines (inter-process transport like ipc).
|
|
|
|
NOTE: Communication between a virtual machine and the host is not supported on Mac OS X 10.9 and above.
|
|
|
|
|
|
ADDRESSING
|
|
----------
|
|
A 0MQ endpoint is a string consisting of a 'transport'`://` followed by an
|
|
'address'. The 'transport' specifies the underlying protocol to use. The
|
|
'address' specifies the transport-specific address to connect to.
|
|
|
|
For the VMCI transport, the transport is `vmci`, and the meaning of
|
|
the 'address' part is defined below.
|
|
|
|
|
|
Binding a socket
|
|
~~~~~~~~~~~~~~~~
|
|
When binding a 'socket' to a local address using _zmq_bind()_ with the 'vmci'
|
|
transport, the 'endpoint' shall be interpreted as an 'interface' followed by a
|
|
colon and the TCP port number to use.
|
|
|
|
An 'interface' may be specified by either of the following:
|
|
|
|
* The wild-card `*`, meaning all available interfaces.
|
|
* An integer returned by `VMCISock_GetLocalCID` or `@` (ZeroMQ will call VMCISock_GetLocalCID internally).
|
|
|
|
The port may be specified by:
|
|
|
|
* A numeric value, usually above 1024 on POSIX systems.
|
|
* The wild-card `*`, meaning a system-assigned ephemeral port.
|
|
|
|
Unbinding wild-card address from a socket
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
When wild-card `*` 'endpoint' was used in _zmq_bind()_, the caller should use
|
|
real 'endpoint' obtained from the ZMQ_LAST_ENDPOINT socket option to unbind
|
|
this 'endpoint' from a socket using _zmq_unbind()_.
|
|
|
|
Connecting a socket
|
|
~~~~~~~~~~~~~~~~~~~
|
|
When connecting a socket to a peer address using _zmq_connect()_ with the 'vmci'
|
|
transport, the 'endpoint' shall be interpreted as a 'peer address' followed by
|
|
a colon and the port number to use.
|
|
|
|
A 'peer address' must be a CID of the peer.
|
|
|
|
|
|
EXAMPLES
|
|
--------
|
|
.Assigning a local address to a socket
|
|
----
|
|
// VMCI port 5555 on all available interfaces
|
|
rc = zmq_bind(socket, "vmci://*:5555");
|
|
assert (rc == 0);
|
|
// VMCI port 5555 on the local loop-back interface on all platforms
|
|
cid = VMCISock_GetLocalCID();
|
|
sprintf(endpoint, "vmci://%d:5555", cid);
|
|
rc = zmq_bind(socket, endpoint);
|
|
assert (rc == 0);
|
|

|
|
|
|
.Connecting a socket
|
|
----
|
|
// Connecting using a CID
|
|
sprintf(endpoint, "vmci://%d:5555", cid);
|
|
rc = zmq_connect(socket, endpoint);
|
|
assert (rc == 0);
