<dd><p>Return an informational structure-array with one entry for each machine specified by <var>connections</var>.
</p>
<p>This function can only be successfully called at the client
machine. See <code>pconnect</code> for a description of the
<var>connections</var> variable. <var>connections</var> can contain all
connections of the network, a subset of them, or a single
connection. For the local machine (client), if contained in
<var>connections</var>, some fields of the returned structure may be
empty.
</p>
<p>The fields of the returned structure are <code>local_machine</code>: true
for the connection representing the local machine, <code>nproc</code>:
number of usable processors of the machine, <code>nlocaljobs</code>:
configured number of local processes on the machine, <code>peername</code>:
name of the machine (empty for local machine), <code>open</code>: true if
the connection is open, <code>network_id</code>: uuid of the network,
<code>real_node_id</code>: internal id assigned to node, <code>0</code> for
client, servers starting with <code>1</code>.
