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);
