<a name="GDataUploadStream.description"></a><h2>Description</h2>
<p><a class="link" href="GDataUploadStream.html" title="GDataUploadStream"><span class="type">GDataUploadStream</span></a> is a <span class="type">GOutputStream</span> subclass to allow uploading of files from GData services with authorization from a <a class="link" href="GDataService.html" title="GDataService"><span class="type">GDataService</span></a> under
the given <a class="link" href="GDataAuthorizationDomain.html" title="GDataAuthorizationDomain"><span class="type">GDataAuthorizationDomain</span></a>. If authorization is not required to perform the upload, a <a class="link" href="GDataAuthorizationDomain.html" title="GDataAuthorizationDomain"><span class="type">GDataAuthorizationDomain</span></a> doesn't have to be
specified.</p>
<p>Once a <a class="link" href="GDataUploadStream.html" title="GDataUploadStream"><span class="type">GDataUploadStream</span></a> is instantiated with <a class="link" href="GDataUploadStream.html#gdata-upload-stream-new" title="gdata_upload_stream_new ()"><code class="function">gdata_upload_stream_new()</code></a>, the standard <span class="type">GOutputStream</span> API can be used on the stream to upload
the file. Network communication may not actually begin until the first call to <code class="function">g_output_stream_write()</code>, so having a <a class="link" href="GDataUploadStream.html" title="GDataUploadStream"><span class="type">GDataUploadStream</span></a> around is no
guarantee that data is being uploaded.</p>
<p>Uploads of a file, or a file with associated metadata (a <a class="link" href="GDataEntry.html" title="GDataEntry"><span class="type">GDataEntry</span></a>) should use <a class="link" href="GDataUploadStream.html" title="GDataUploadStream"><span class="type">GDataUploadStream</span></a>, but if you want to simply upload a single
<a class="link" href="GDataEntry.html" title="GDataEntry"><span class="type">GDataEntry</span></a>, use <a class="link" href="GDataService.html#gdata-service-insert-entry" title="gdata_service_insert_entry ()"><code class="function">gdata_service_insert_entry()</code></a> instead. <a class="link" href="GDataUploadStream.html" title="GDataUploadStream"><span class="type">GDataUploadStream</span></a> is for large streaming uploads.</p>
<p>Once an upload is complete, the server's response can be retrieved from the <a class="link" href="GDataUploadStream.html" title="GDataUploadStream"><span class="type">GDataUploadStream</span></a> using <a class="link" href="GDataUploadStream.html#gdata-upload-stream-get-response" title="gdata_upload_stream_get_response ()"><code class="function">gdata_upload_stream_get_response()</code></a>. In order
for network communication to be guaranteed to have stopped (and thus the response definitely available), <code class="function">g_output_stream_close()</code> must be called
on the <a class="link" href="GDataUploadStream.html" title="GDataUploadStream"><span class="type">GDataUploadStream</span></a> first. Otherwise, <a class="link" href="GDataUploadStream.html#gdata-upload-stream-get-response" title="gdata_upload_stream_get_response ()"><code class="function">gdata_upload_stream_get_response()</code></a> may return saying that the operation is still in progress.</p>
<p>If the server returns an error instead of a success response, the error will be returned by <code class="function">g_output_stream_close()</code> as a <a class="link" href="GDataService.html#GDataServiceError" title="enum GDataServiceError"><span class="type">GDataServiceError</span></a>.</p>
<p>The entire upload operation can be cancelled using the <span class="type">GCancellable</span> instance provided to <a class="link" href="GDataUploadStream.html#gdata-upload-stream-new" title="gdata_upload_stream_new ()"><code class="function">gdata_upload_stream_new()</code></a>, or returned by
<a class="link" href="GDataUploadStream.html#gdata-upload-stream-get-cancellable" title="gdata_upload_stream_get_cancellable ()"><code class="function">gdata_upload_stream_get_cancellable()</code></a>. Cancelling this at any time will cause all future <span class="type">GOutputStream</span> method calls to return
<code class="literal">G_IO_ERROR_CANCELLED</code>. If any <span class="type">GOutputStream</span> methods are in the process of being called, they will be cancelled and return <code class="literal">G_IO_ERROR_CANCELLED</code> as
soon as possible.</p>
<p>Note that cancelling an individual method call (such as a call to <code class="function">g_output_stream_write()</code>) using the <span class="type">GCancellable</span> parameter of the method will not
cancel the upload as a whole — just that particular method call. In the case of <code class="function">g_output_stream_write()</code>, this will cause it to return the number of
bytes it has successfully written up to the point of cancellation (up to the requested number of bytes), or return a <code class="literal">G_IO_ERROR_CANCELLED</code> if it
had not managed to write any bytes to the network by that point. This is also the behaviour of <code class="function">g_output_stream_write()</code> when the upload operation as
a whole is cancelled.</p>
<p>In the case of <code class="function">g_output_stream_close()</code>, the call will return immediately if network activity hasn't yet started. If it has, the network activity
will be cancelled, regardless of whether the call to <code class="function">g_output_stream_close()</code> is cancelled. Cancelling a pending call to <code class="function">g_output_stream_close()</code>
(either using the method's <span class="type">GCancellable</span>, or by cancelling the upload stream as a whole) will cause it to stop waiting for the network activity to
finish, and return <code class="literal">G_IO_ERROR_CANCELLED</code> immediately. Network activity will continue to be shut down in the background.</p>
<p>Any outstanding data is guaranteed to be written to the network successfully even if a call to <code class="function">g_output_stream_close()</code> is cancelled. However, if
the upload stream as a whole is cancelled using <a class="link" href="GDataUploadStream.html#GDataUploadStream--cancellable" title="The “cancellable” property"><span class="type">“cancellable”</span></a>, no more data will be sent over the network, and the network
connection will be closed immediately. i.e. <a class="link" href="GDataUploadStream.html" title="GDataUploadStream"><span class="type">GDataUploadStream</span></a> will do its best to instruct the server to cancel the upload and any associated
server-side changes of state.</p>
<p>If the server returns an error message (for example, if the user is not correctly authenticated/authorized or doesn't have suitable permissions
to upload from the given URI), it will be returned as a <a class="link" href="GDataService.html#GDataServiceError" title="enum GDataServiceError"><span class="type">GDataServiceError</span></a> by <code class="function">g_output_stream_close()</code>.</p>

<a name="GDataUploadStream--cancellable"></a><h3>The <code class="literal">“cancellable”</code> property</h3>
<pre class="programlisting"> “cancellable” <span class="type">GCancellable</span> *</pre>
<p>An optional cancellable used to cancel the entire upload operation. If a <span class="type">GCancellable</span> instance isn't provided for this property at
construction time (i.e. to <a class="link" href="GDataUploadStream.html#gdata-upload-stream-new" title="gdata_upload_stream_new ()"><code class="function">gdata_upload_stream_new()</code></a>), one will be created internally and can be retrieved using

<a class="link" href="GDataUploadStream.html#gdata-upload-stream-new" title="gdata_upload_stream_new ()"><code class="function">gdata_upload_stream_new()</code></a>.</p>
<p>If the upload operation is cancelled using this <span class="type">GCancellable</span>, any ongoing network activity will be stopped, and any pending or future calls
to <span class="type">GOutputStream</span> API on the <a class="link" href="GDataUploadStream.html" title="GDataUploadStream"><span class="type">GDataUploadStream</span></a> will return <code class="literal">G_IO_ERROR_CANCELLED</code>. Note that the <span class="type">GCancellable</span> objects which can be passed
to individual <span class="type">GOutputStream</span> operations will not cancel the upload operation proper if cancelled — they will merely cancel that API call.
The only way to cancel the upload operation completely is using <a class="link" href="GDataUploadStream.html#GDataUploadStream--cancellable" title="The “cancellable” property"><span class="type">“cancellable”</span></a>.</p>
