<h2>USAGE</h2>
<p>This function is very similar to <a class="link" href="mail-folderfromstring.html" title="mail::account::folderFromString" shape="rect"><span class="citerefentry"><span class="refentrytitle">mail::account::folderFromString</span>(3x)</span></a>.
<code class="function">mail::account::findFolder</code>
recreates a <span class="structname">mail::folder</span>
object, given its server path (which is returned by <a class="link" href="folder-getpath.html" title="mail::folder::getPath" shape="rect"><span class="citerefentry"><span class="refentrytitle">mail::folder::getPath</span>(3x)</span></a>.
The differences between <code class="function">mail::account::findFolder</code> and <code class="function">mail::account::folderFromString</code> are:</p>
<div class="itemizedlist">
<ul type="disc">
<li>
<p><code class="function">mail::account::folderFromString</code> uses
a string created by <code class="function">mail::account::folder::toString</code>,
which includes all of the folder's properties (such as
whether the folder contains messages, subfolders, or
both, and its canonical name). <code class="function">mail::account::findFolder</code> uses only
the folder's "path", or "address" on the server.</p>
</li>
</ul>
</div>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>The application must not destroy <em class="parameter"><code>folderCallback</code></em> until this
request fails or succeeds. <em class="parameter"><code>folderCallback</code></em>'s <code class="function">success</code> method is invoked just before the
<em class="parameter"><code>callback</code></em>'s
<code class="function">success</code> method.</p>
</div>
<p>The <code class="function">folderCallback.success</code>
method receives a vector with a single pointer <span class="structname">mail::folder</span> object, that's initialized
to represent the folder referenced by <em class="parameter"><code>folderPath</code></em>.</p>
</div>
<div class="refsect1" lang="en" xml:lang="en">
<a id="id586186" shape="rect" name="id586186"> </a>
<h2>RETURN CODES AND CALLBACKS</h2>
<p>The application must wait until <em class="parameter"><code>callback</code></em>'s <code class="function">success</code> or <code class="function">fail</code> method is invoked. The <code class="function">success</code> method is invoked when this request
is succesfully processed. The <code class="function">fail</code> method is invoked if this request
cannot be processed. The application must not destroy
<em class="parameter"><code>callback</code></em> until either
the <code class="function">success</code> or <code class="function">fail</code> method is invoked.</p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p><em class="parameter"><code>callback</code></em>'s
<code class="function">fail</code> method may be invoked
even after other callback methods were invoked. This
indicates that the request was partially completed before
the error was encountered.</p>
</div>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>The <code class="function">folderCallback.success</code>
method receives a (possibly empty) vector of pointers to
<span class="structname">mail::folder</span> objects. These
objects will be destroyed when <code class="function">folderCallback.success</code> terminates. The
application must use <a class="link" href="folder-clone.html" title="mail::folder::clone" shape="rect"><span class="citerefentry"><span class="refentrytitle">mail::folder::clone</span>(3x)</span></a>
to create copies of <span class="structname">mail::folder</span> objects it wants to use
later.</p>
</div>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p>Both <code class="function">folderCallback.success</code> and <code class="function">myCallback.success</code> method will be invoked
if this request succeeds. <code class="function">folderCallback.success</code> will be invoked
before <code class="function">myCallback.success</code>
(since by definition this indicates that the request has
been completed).</p>
</div>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<h3 class="title">Note</h3>
<p><span class="structname">mail::folder</span>s are linked
to their corresponding <span class="structname">mail::account</span>s. A <span class="structname">mail::folder</span> created by one
<span class="structname">mail::account</span> may not be
used with a different <span class="structname">mail::folder</span>. All <span class="structname">mail::folder</span>s created by a <span class="structname">mail::account</span> are invalidated when this
<span class="structname">mail::account</span> object is
destroyed. Note that the <span class="structname">mail::folder</span> objects are not
automatically destroyed; the application is still
responsible for destroying any remaining <span class="structname">mail::folder</span>s, after their a
<span class="structname">mail::account</span> is
destroyed.</p>
