## Object Hierarchy

        GObject
        ╰── GUnixMountMonitor

## Includes

    #include <gio/gunixmounts.h>

## Description

Routines for managing mounted UNIX mount points and paths.

Note that `<gio/gunixmounts.h>` belongs to the UNIX-specific GIO interfaces, thus you have to use the `gio-unix-2.0.pc` pkg-config file when using it.

Since: 2.44

### g_unix_mount_monitor_new ()

    GUnixMountMonitor *
    g_unix_mount_monitor_new (void);

`g_unix_mount_monitor_new` has been deprecated since version 2.44 and should not be used in newly-written code.

Use `g_unix_mount_monitor_get()` instead.

Deprecated alias for `g_unix_mount_monitor_get()`.

This function was never a true constructor, which is why it was renamed.

#### Returns

a GUnixMountMonitor.

### g_unix_mount_monitor_set_rate_limit ()

    void
    g_unix_mount_monitor_set_rate_limit (GUnixMountMonitor *mount_monitor,

`g_unix_mount_monitor_set_rate_limit` has been deprecated since version 2.44 and should not be used in newly-written code.

This function does nothing. Don't call it.

This function does nothing.

Before 2.44, this was a partially-effective way of controlling the rate at which events would be reported under some uncommon circumstances. Since `mount_monitor` is a singleton, it also meant that calling this function would have side effects for other users of the monitor.

#### Parameters

mount_monitor | a GUnixMountMonitor |
limit_msec | a integer with the limit in milliseconds to poll for changes. |

Since: 2.18

### g_unix_is_mount_path_system_internal ()

    gboolean
    g_unix_is_mount_path_system_internal (const char *mount_path);

Determines if `mount_path` is considered an implementation of the OS. This is primarily used for hiding mountable and mounted volumes that only are used in the OS and has little to no relevance to the casual user.

#### Parameters

mount_path | a mount path, e.g. `/media/disk` or `/usr` |

#### Returns

`TRUE` if `mount_path` is considered an implementation detail of the OS.

## Types and Values

### GUnixMountPoint

    typedef struct _GUnixMountPoint GUnixMountPoint;

Defines a Unix mount point (e.g. <filename>/dev</filename>). This corresponds roughly to a fstab entry.

### GUnixMountEntry

    typedef struct _GUnixMountEntry GUnixMountEntry;

Defines a Unix mount entry (e.g. <filename>/media/cdrom</filename>). This corresponds roughly to a mtab entry.

### GUnixMountMonitor

    typedef struct _GUnixMountMonitor GUnixMountMonitor;

Watches GUnixMounts for changes.
