<a name="JsonrpcClient.description"></a><h2>Description</h2>
<p>The <a class="link" href="JsonrpcClient.html" title="JsonrpcClient"><span class="type">JsonrpcClient</span></a> class provides a convenient API to coordinate with a
JSON-RPC server. You can provide the underlying <span class="type">GIOStream</span> to communicate
with allowing you to control the negotiation of how you setup your
communications channel. One such method might be to use a <span class="type">GSubprocess</span> and
communicate over stdin and stdout.</p>
<p>Because JSON-RPC allows for out-of-band notifications from the server to
the client, it is important that the consumer of this API calls
<a class="link" href="JsonrpcClient.html#jsonrpc-client-close" title="jsonrpc_client_close ()"><code class="function">jsonrpc_client_close()</code></a> or <a class="link" href="JsonrpcClient.html#jsonrpc-client-close-async" title="jsonrpc_client_close_async ()"><code class="function">jsonrpc_client_close_async()</code></a> when they no longer
need the client. This is because <a class="link" href="JsonrpcClient.html" title="JsonrpcClient"><span class="type">JsonrpcClient</span></a> contains an asynchronous
read-loop to process incoming messages. Until <a class="link" href="JsonrpcClient.html#jsonrpc-client-close" title="jsonrpc_client_close ()"><code class="function">jsonrpc_client_close()</code></a> or
<a class="link" href="JsonrpcClient.html#jsonrpc-client-close-async" title="jsonrpc_client_close_async ()"><code class="function">jsonrpc_client_close_async()</code></a> have been called, this read loop will prevent
the object from finalizing (being freed).</p>
<p>To make an RPC call, use <a class="link" href="JsonrpcClient.html#jsonrpc-client-call" title="jsonrpc_client_call ()"><code class="function">jsonrpc_client_call()</code></a> or
<a class="link" href="JsonrpcClient.html#jsonrpc-client-call-async" title="jsonrpc_client_call_async ()"><code class="function">jsonrpc_client_call_async()</code></a> and provide the method name and the parameters
as a <span class="type">GVariant</span> for call.</p>
<p>It is a programming error to mix synchronous and asynchronous API calls
of the <a class="link" href="JsonrpcClient.html" title="JsonrpcClient"><span class="type">JsonrpcClient</span></a> class.</p>
<p>For synchronous calls, <a class="link" href="JsonrpcClient.html" title="JsonrpcClient"><span class="type">JsonrpcClient</span></a> will use the thread-default
<span class="type">GMainContext</span>. If you have special needs here ensure you've set the context
before calling into any <a class="link" href="JsonrpcClient.html" title="JsonrpcClient"><span class="type">JsonrpcClient</span></a> API.</p>

<p>This signal is emitted when an RPC has been received from the peer we
are connected to. Return <code class="literal">TRUE</code> if you have handled this message, even
asynchronously. If no handler has returned <code class="literal">TRUE</code> an error will be
synthesized.</p>
<p>If you handle the message, you are responsible for replying to the peer
in a timely manner using <a class="link" href="JsonrpcClient.html#jsonrpc-client-reply" title="jsonrpc_client_reply ()"><code class="function">jsonrpc_client_reply()</code></a> or
<a class="link" href="JsonrpcClient.html#jsonrpc-client-reply-async" title="jsonrpc_client_reply_async ()"><code class="function">jsonrpc_client_reply_async()</code></a>.</p>
<p>Additionally, since 3.28 you may connect to the "detail" of this signal
to handle a specific method call. Use the method name as the detail of
the signal.</p>
