## Object Hierarchy

        GObject
        ╰── GSSDPClient
            ╰── GUPnPContext

## Implemented Interfaces

GUPnPContext implements GInitable.

## Description

GUPnPContext wraps the networking bits that are used by the various GUPnP classes. It automatically starts a web server on demand.

For debugging, it is possible to see the messages being sent and received by exporting `GUPNP_DEBUG`.

## Functions

### gupnp_context_new ()

    GUPnPContext *
    gupnp_context_new (GMainContext *main_context,
                       const char *iface,
                       guint port,
                       GError **error);

Create a new GUPnPContext with the specified `main_context` , `iface` and `port` .

#### Parameters

main_context | Deprecated: 0.17.2: Always set to `NULL`. If you want to use a different context, use `g_main_context_push_thread_default()`. | [allow-none]
iface | The network interface to use, or `NULL` to auto-detect. | [allow-none]
port | Port to run on, or 0 if you don't care what port is used. |
error | A location to store a GError, or `NULL` |

#### Returns

A new GUPnPContext object, or `NULL` on an error

### gupnp_context_get_host_ip ()

    const char *
    gupnp_context_get_host_ip (GUPnPContext *context);

`gupnp_context_get_host_ip` has been deprecated since version 0.12.7 and should not be used in newly-written code.

The "host-ip" property has moved to the base class GSSDPClient so newer applications should use gssdp_client_get_host_ip instead.

#### Parameters

context | A GUPnPContext |

#### Returns

The IP address. This string should not be freed.

### gupnp_context_get_port ()

    guint
    gupnp_context_get_port (GUPnPContext *context);

`gupnp_context_get_port` is deprecated and should not be used in newly-written code.

Get the port that the SOAP server is running on.

#### Parameters

context | A GUPnPContext |

#### Returns

The port the SOAP server is running on.

### gupnp_context_get_server ()

    SoupServer *
    gupnp_context_get_server (GUPnPContext *context);

Get the SoupServer HTTP server that GUPnP is using.

#### Parameters

context | A GUPnPContext |

#### Returns

The SoupServer used by GUPnP. Do not unref this when finished.

[transfer none]

### gupnp_context_get_session ()

    SoupSession *
    gupnp_context_get_session (GUPnPContext *context);

Get the SoupSession object that GUPnP is using.

#### Parameters

context | A GUPnPContext |

                                    guint timeout);

Sets the event subscription timeout to `timeout` . Use 0 if you don't want subscriptions to time out. Note that any client side subscriptions will automatically be renewed.

#### Parameters

context | A GUPnPContext |
timeout | Event subscription timeout in seconds |

### gupnp_context_get_subscription_timeout ()

    guint
    gupnp_context_get_subscription_timeout
                                   (GUPnPContext *context);

Get the event subscription timeout (in seconds), or 0 meaning there is no timeout.

#### Parameters

context | A GUPnPContext |

#### Returns

The event subscription timeout in seconds.

### gupnp_context_get_default_language ()

    const char *
    gupnp_context_get_default_language (GUPnPContext *context);

Get the default Content-Language header for this context.

#### Parameters

                                        const char *language);

Set the default language for the Content-Length header to `language` .

If the client sends an Accept-Language header the UPnP HTTP server is required to send a Content-Language header in return. If there are no files hosted in languages which match the requested ones the Content-Language header is set to this value. The default value is "en".

#### Parameters

context | A GUPnPContext |
language | A language tag as defined in RFC 2616 3.10 |
