to close a stream (<a class="link" href="GOutputStream.html#g-output-stream-close" title="g_output_stream_close ()"><code class="function">g_output_stream_close()</code></a>) and to flush pending writes
(<a class="link" href="GOutputStream.html#g-output-stream-flush" title="g_output_stream_flush ()"><code class="function">g_output_stream_flush()</code></a>). </p>
<p>To copy the content of an input stream to an output stream without
manually handling the reads and writes, use <a class="link" href="GOutputStream.html#g-output-stream-splice" title="g_output_stream_splice ()"><code class="function">g_output_stream_splice()</code></a>.</p>
<p>See the documentation for <a class="link" href="GIOStream.html" title="GIOStream"><span class="type">GIOStream</span></a> for details of thread safety of

<p>Tries to write <em class="parameter"><code>count</code></em>
bytes from <em class="parameter"><code>buffer</code></em>
into the stream. Will block
during the operation.</p>
<p>If count is 0, returns 0 and does nothing. A value of <em class="parameter"><code>count</code></em>
larger than <a href="../glib-Basic-Types.html#G-MAXSSIZE:CAPS"><code class="literal">G_MAXSSIZE</code></a> will cause a <a class="link" href="gio-GIOError.html#G-IO-ERROR-INVALID-ARGUMENT:CAPS"><code class="literal">G_IO_ERROR_INVALID_ARGUMENT</code></a> error.</p>
<p>On success, the number of bytes written to the stream is returned.
It is not an error if this is not the same as the requested size, as it
can happen e.g. on a partial I/O error, or if there is not enough
storage in the stream. All writes block until at least one byte
is written or an error occurs; 0 is never returned (unless
<em class="parameter"><code>count</code></em>
is 0).</p>
<p>If <em class="parameter"><code>cancellable</code></em>
is not <a href="../glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error <a class="link" href="gio-GIOError.html#G-IO-ERROR-CANCELLED:CAPS"><code class="literal">G_IO_ERROR_CANCELLED</code></a> will be returned. If an
operation was partially finished when the operation was cancelled the
partial result will be returned, without an error.</p>
<p>On error -1 is returned and <em class="parameter"><code>error</code></em>
is set accordingly.</p>

<p>Once the stream is closed, all other operations will return <a class="link" href="gio-GIOError.html#G-IO-ERROR-CLOSED:CAPS"><code class="literal">G_IO_ERROR_CLOSED</code></a>.
Closing a stream multiple times will not return an error.</p>
<p>Closing a stream will automatically flush any outstanding buffers in the

<p>Streams will be automatically closed when the last reference
is dropped, but you might want to call this function to make sure
resources are released as early as possible.</p>
<p>Some streams might keep the backing store of the stream (e.g. a file descriptor)
open after the stream is closed. See the documentation for the individual
stream for details.</p>
<p>On failure the first error that happened will be reported, but the close
operation will finish as much as possible. A stream that failed to
close will still return <a class="link" href="gio-GIOError.html#G-IO-ERROR-CLOSED:CAPS"><code class="literal">G_IO_ERROR_CLOSED</code></a> for all operations. Still, it
is important to check and report the error to the user, otherwise
there might be a loss of data as all data might not be written.</p>
<p>If <em class="parameter"><code>cancellable</code></em>
is not <a href="../glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>, then the operation can be cancelled by

was cancelled, the error <a class="link" href="gio-GIOError.html#G-IO-ERROR-CANCELLED:CAPS"><code class="literal">G_IO_ERROR_CANCELLED</code></a> will be returned.
Cancelling a close will still leave the stream closed, but there some streams
can use a faster close that doesn't block to e.g. check errors. On
cancellation (as with any error) there is no guarantee that all written
data will reach the target.</p>
