<a name="tp-verify-statement"></a><h3>tp_verify_statement()</h3>
<pre class="programlisting">#define tp_verify_statement(R) ((void) tp_verify_true (R))
</pre>
<p>Make an assertion at compile time, like C++0x's proposed static_assert
keyword. If <em class="parameter"><code>R</code></em>
is determined to be true, there is no overhead at runtime;
if <em class="parameter"><code>R</code></em>
is determined to be false, compilation will fail.</p>
<p>This macro can be used anywhere that a statement would be allowed; it
is equivalent to ((void) tp_verify_true (R)).</p>
<p>This macro will be deprecated in a future telepathy-glib release. Please
use GLib 2.20's <code class="function">G_STATIC_ASSERT()</code> macro in new code.</p>

<p>Escape an arbitrary string so it follows the rules for a C identifier,
and hence an object path component, interface element component,
bus name component or member name in D-Bus.</p>
<p>Unlike g_strcanon this is a reversible encoding, so it preserves
distinctness.</p>
<p>The escaping consists of replacing all non-alphanumerics, and the first
character if it's a digit, with an underscore and two lower-case hex
digits:</p>
<p> "0123abc_xyz\x01\xff" -> _30123abc_5fxyz_01_ff</p>
<p>i.e. similar to URI encoding, but with _ taking the role of %, and a
smaller allowed set. As a special case, "" is escaped to "_" (just for
completeness, really).</p>

<a name="TpWeakRef"></a><h3>TpWeakRef</h3>
<pre class="programlisting">typedef struct _TpWeakRef TpWeakRef;</pre>
<p>A simple wrapper for a weak reference to a <span class="type">GObject</span>, suitable for use in
asynchronous calls which should only affect the object if it hasn't already
been freed.</p>
<p>As well as wrapping a weak reference to an object, this structure can
contain an extra pointer to arbitrary data. This is useful for asynchronous
calls which act on an object and some second piece of data, which are quite
common in practice.</p>
<p>If more than one piece of auxiliary data is required, the <em class="parameter"><code>user_data</code></em>
argument to the constructor can be a struct or a <span class="type">GValueArray</span>.</p>
