## Description

A Utility class that takes care of creation and destruction of GUPnPContext objects for all available network interfaces as they go up (connect) and down (disconnect), respectively.

## Functions

### gupnp_context_manager_new ()

    GUPnPContextManager *
    gupnp_context_manager_new (GMainContext *main_context,
                               guint port);

`gupnp_context_manager_new` has been deprecated since version 0.17.2 and should not be used in newly-written code.

Use `gupnp_context_manager_create()`.

Same as `gupnp_context_manager_create()`.

#### Parameters

main_context | Deprecated: 0.17.2: `NULL`. If you want to use a different main context use `g_main_context_push_thread_default()` instead. | [allow-none]
port | Port to create contexts for, or 0 if you don't care what port is used. |

#### Returns

A new GUPnPContextManager object.

[transfer full]

Since: 0.13.0

### gupnp_context_manager_create ()

    GUPnPContextManager *
    gupnp_context_manager_create (guint port);

Factory-method to create a new GUPnPContextManager. The final type of the GUPnPContextManager depends on the compile-time selection or - in case of NetworkManager - on its availability during runtime. If it is not available, the implementation falls back to the basic Unix context manager instead.

#### Parameters

port | Port to create contexts for, or 0 if you don't care what port is used. |

#### Returns

A new GUPnPContextManager object.

[transfer full]

Since: 0.17.2

### gupnp_context_manager_rescan_control_points ()

    void
    gupnp_context_manager_rescan_control_points
                                   (GUPnPContextManager *manager);

This function starts a rescan on every control point managed by `manager` . Only the active control points send discovery messages. This function should be called when servers are suspected to have disappeared.

#### Parameters

manager | A GUPnPContextManager |

Since: 0.20.3

### gupnp_context_manager_manage_control_point ()

    void
    gupnp_context_manager_manage_control_point
                                   (GUPnPContextManager *manager,
                                    GUPnPControlPoint *control_point);

By calling this function, you are asking `manager` to keep a reference to `control_point` until its associated GUPnPContext is no longer available. You usually want to call this function from “context-available” handler after you create a GUPnPControlPoint object for the newly available context.

#### Parameters

manager | A GUPnPContextManager |
control_point | The GUPnPControlPoint to be taken care of |

Since: 0.13.0

### gupnp_context_manager_manage_root_device ()

    void
    gupnp_context_manager_manage_root_device
                                   (GUPnPContextManager *manager,
                                    GUPnPRootDevice *root_device);

By calling this function, you are asking `manager` to keep a reference to `root_device` when its associated GUPnPContext is no longer available. You usually want to call this function from “context-available” handler after you create a GUPnPRootDevice object for the newly available context.

#### Parameters

manager | A GUPnPContextManager |
root_device | The GUPnPRootDevice to be taken care of |

Since: 0.13.0

### gupnp_context_manager_get_port ()

    guint
    gupnp_context_manager_get_port (GUPnPContextManager *manager);

Get the network port associated with this context manager.

#### Parameters

manager | A GUPnPContextManager |

#### Returns

The network port asssociated with this context manager.

Since: 0.19.1

### gupnp_context_manager_get_white_list ()

    GUPnPWhiteList *
    gupnp_context_manager_get_white_list (GUPnPContextManager *manager);

Get the GUPnPWhiteList associated with `manager` .

#### Parameters

manager | A GUPnPContextManager |

#### Returns

The GUPnPWhiteList asssociated with this context manager.

[transfer none]

## Signal Details

### The `“context-available”` signal

    void
    user_function (GUPnPContextManager *context_manager,
                   GUPnPContext        *context,
                   gpointer             user_data)

Signals the availability of new GUPnPContext.

#### Parameters

context_manager | The GUPnPContextManager that received the signal |
context | The now available GUPnPContext |
user_data | user data set when the signal handler was connected. |

Flags: Run First

### The `“context-unavailable”` signal

    void
