## Implemented Interfaces

GdictClientContext implements

## Description

GdictClientContext is an implementation of the GdictContext interface. It implements the Dictionary Protocol as defined by the RFC 2229 in order to connect to a dictionary server.

You should rarely instantiate this object directely: use an appropriate GdictSource instead.

## Functions

### gdict_client_context_new ()

    GdictContext *
    gdict_client_context_new (const gchar *hostname,
                              gint port);

Creates a new GdictClientContext object for `hostname` . Use this object to connect and query the dictionary server using the Dictionary Protocol as defined by RFC 2229.

#### Parameters

hostname | the hostname of a dictionary server, or `NULL` for the default server. | [nullable]
port | port to be used when connecting to the dictionary server, or -1 for the default port |

#### Returns

the newly created GdictClientContext object.

[transfer full]

### gdict_client_context_set_hostname ()

                                       const gchar *hostname);

Sets `hostname` as the hostname of the dictionary server to be used. If `hostname` is `NULL`, the default dictionary server will be used.

Gets the hostname of the dictionary server used by `context` .

#### Parameters

context | a GdictClientContext |

#### Returns

the hostname of a dictionary server. The returned string is owned by the GdictClientContext object and should never be modified or freed.

Sets the port of the dictionary server to be used when connecting.

If `port` is -1, the default port will be used.

#### Parameters

context | a GdictClientContext |
port | port of the dictionary server to be used, or -1 |

### gdict_client_context_get_port ()

#### Parameters

context | a GdictClientContext |

#### Returns

the number of the port.

### gdict_client_context_set_client ()

Sets `client` as the client name to be used when advertising ourselves when a connection the the dictionary server has been established. If `client` is `NULL`, the default client name will be used.

#### Parameters

context | a GdictClientContext |
client | the client name to use, or `NULL`. | [nullable]

### gdict_client_context_get_client ()

    const gchar *
    gdict_client_context_get_client (GdictClientContext *context);

#### Parameters

context | a GdictClientContext |

the client name. The returned string is owned by the GdictClientContext object and should never be modified or freed.
