to handle this. See <a class="link" href="gnome-vfs-2.0-gnome-vfs-async-ops.html#gnome-vfs-async-cancel" title="gnome_vfs_async_cancel ()"><code class="function">gnome_vfs_async_cancel()</code></a> for more

<p>
Get a file descriptor -based notificator for <em class="parameter"><code>cancellation</code></em>.  When
<em class="parameter"><code>cancellation</code></em> receives a cancellation request, a character will be made
available on the returned file descriptor for input.
</p>
<p>
This is very useful for detecting cancellation during I/O operations: you
can use the <code class="function">select()</code> call to check for available input/output on the file
you are reading/writing, and on the notificator's file descriptor at the
same time.  If a data is available on the notificator's file descriptor, you
know you have to cancel the read/write operation.
