class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a> interface represents user-visible mounts. Note, when porting from GnomeVFS, <a class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a> is the moral equivalent of <span class="type">GnomeVFSVolume</span>.</p><p><a class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a> is a "mounted" filesystem that you can access. Mounted is inquotes because it's not the same as a unix mount, it might be a gvfsmount, but you can still access the files on it if you use GIO. Might ormight not be related to a volume object.</p><p>Unmounting a <a class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a> instance is an asynchronous operation. Formore information about asynchronous operations, see <span class="type">GAsyncReady</span>and <span class="type">GSimpleAsyncReady</span>. To unmount a <a class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a> instance, first call<a class="link" href="GMount.html#g-mount-unmount"><code class="function">g_mount_unmount()</code></a> with (at least) the <a class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a> instance and a<a class="link" href="GAsyncResult.html#GAsyncReadyCallback"><span class="type">GAsyncReadyCallback</span></a>. The callback will be fired when theoperation has resolved (either with success or failure), and a<span class="type">GAsyncReady</span> structure will be passed to the callback. Thatcallback should then call <a class="link" href="GMount.html#g-mount-unmount-finish"><code class="function">g_mount_unmount_finish()</code></a> with the <a class="link" href="GMount.html" title="GMount"><span class="type">GMount</span></a>and the <span class="type">GAsyncReady</span> data to see if the operation was completedsuccessfully. If an <em class="parameter"><code>error</code></em> is present when <a class="link" href="GMount.html#g-mount-unmount-finish"><code class="function">g_mount_unmount_finish()</code></a> is called, then it will be filled with any error information.</p><p></p></div><div class="refsect1" lang="en"><a name="id3213054"></a><h2>Details</h2><div class="refsect2" lang="en"><a name="id3224563"></a><h3><a name="GMount-struct"></a>GMount</h3><a class="indexterm" name="id3224575"></a><pre class="programlisting">typedef struct _GMount GMount;</pre><p>A handle to an object implementing the <a class="link" href="GMount.html#GMountIface"><span class="type">GMountIface</span></a> interface.</p><p></p></div><hr><div class="refsect2" lang="en"><a name="id3224601"></a><h3><a name="GMountIface"></a>GMountIface</h3><a class="indexterm" name="id3224613"></a><pre class="programlisting">typedef struct { GTypeInterface g_iface; /* signals */ void (*changed) (GMount *mount); void (*unmounted) (GMount *mount); /* Virtual Table */ GFile * (*get_root) (GMount *mount); char * (*get_name) (GMount *mount); GIcon * (*get_icon) (GMount *mount); char * (*get_uuid) (GMount *mount); GVolume * (*get_volume) (GMount *mount); GDrive * (*get_drive) (GMount *mount); gboolean (*can_unmount) (GMount *mount); gboolean (*can_eject) (GMount *mount); void (*unmount) (GMount *mount, GMountUnmountFlags flags, GCancellable *cancellable, GAsyncReadyCallback callback, gpointer user_data); gboolean (*unmount_finish) (GMount *mount, GAsyncResult *result, GError **error); void (*eject) (GMount *mount, GMountUnmountFlags flags, GCancellable *cancellable, GAsyncReadyCallback callback, gpointer user_data); gboolean (*eject_finish) (GMount *mount, GAsyncResult *result, GError **error); void (*remount) (GMount *mount, GMountMountFlags flags, GMountOperation *mount_operation, GCancellable *cancellable, GAsyncReadyCallback callback, gpointer user_data); gboolean (*remount_finish) (GMount *mount, GAsyncResult *result, GError **error);} GMountIface;</pre><p>Interface for implementing operations for mounts.</p><p></p><div class="variablelist"><table border="0">⌨️ 快捷键说明
