## Functions

### TpSimpleHandlerHandleChannelsImpl ()

    void
    (*TpSimpleHandlerHandleChannelsImpl) (TpSimpleHandler *handler,
                                          TpAccount *account,
                                          TpConnection *connection,
                                          GList *channels,
                                          GList *requests_satisfied,
                                          gint64 user_action_time,
                                          TpHandleChannelsContext *context,
                                          gpointer user_data);

Signature of the implementation of the HandleChannels method.

This function must call either `tp_handle_channels_context_accept()`, `tp_handle_channels_context_delay()` or `tp_handle_channels_context_fail()` on `context` before it returns.

#### Parameters

handler | a TpSimpleHandler instance |
account | a TpAccount having `TP_ACCOUNT_FEATURE_CORE` prepared if possible |
connection | a TpConnection having `TP_CONNECTION_FEATURE_CORE` prepared if possible |
channels | a GList of TpChannel, all having `TP_CHANNEL_FEATURE_CORE` prepared if possible. | [element-type TelepathyGLib.Channel]
requests_satisfied | a GList of TpChannelRequest having their object-path defined but are not guaranteed to be prepared. | [element-type TelepathyGLib.ChannelRequest]
user_action_time | the time at which user action occurred, or one of the special values `TP_USER_ACTION_TIME_NOT_USER_ACTION` or `TP_USER_ACTION_TIME_CURRENT_TIME` (see “user-action-time” for details) |
context | a TpHandleChannelsContext representing the context of this D-Bus call |
user_data | arbitrary user-supplied data passed to `tp_simple_handler_new()` |

Since 0.11.6

### tp_simple_handler_new ()

    TpBaseClient *
    tp_simple_handler_new (TpDBusDaemon *dbus,
                           gboolean bypass_approval,
                           gboolean requests,
                           const gchar *name,
                           gboolean uniquify,
                           TpSimpleHandlerHandleChannelsImpl callback,
                           gpointer user_data,
                           GDestroyNotify destroy);

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

New code should use `tp_simple_handler_new_with_am()` instead.

Convenient function to create a new TpSimpleHandler instance.

If `dbus` is not the result of `tp_dbus_daemon_dup()`, you should call `tp_simple_handler_new_with_am()` instead, so that TpAccount, TpConnection and TpContact instances can be shared between modules.

#### Parameters

dbus | a TpDBusDaemon object, may not be `NULL` |
bypass_approval | the value of the Handler.BypassApproval D-Bus property (see `tp_base_client_set_handler_bypass_approval()` for details) |
requests | whether this handler should implement Requests (see `tp_base_client_set_handler_request_notification()` for details) |
name | the name of the Handler (see “name” for details) |
uniquify | the value of the “uniquify-name” property |
callback | the function called when HandleChannels is called |
user_data | arbitrary user-supplied data passed to `callback` |
destroy | called with `user_data` as its argument when the TpSimpleHandler is destroyed |

#### Returns

a new TpSimpleHandler.

### tp_simple_handler_new_with_am ()

    TpBaseClient *
    tp_simple_handler_new_with_am (TpAccountManager *account_manager,
                                   gboolean bypass_approval,
                                   gboolean requests,
                                   const gchar *name,
                                   gboolean uniquify,
                                   TpSimpleHandlerHandleChannelsImpl callback,
                                   gpointer user_data,
                                   GDestroyNotify destroy);

Convenient function to create a new TpSimpleHandler instance with a specified TpAccountManager.

It is not necessary to prepare any features on `account_manager` before calling this function.

#### Parameters

account_manager | an account manager, which may not be `NULL` |
bypass_approval | the value of the Handler.BypassApproval D-Bus property (see `tp_base_client_set_handler_bypass_approval()` for details) |
requests | whether this handler should implement Requests (see `tp_base_client_set_handler_request_notification()` for details) |
name | the name of the Handler (see “name” for details) |
uniquify | the value of the “uniquify-name” property |
callback | the function called when HandleChannels is called |
user_data | arbitrary user-supplied data passed to `callback` |
destroy | called with `user_data` as its argument when the TpSimpleHandler is destroyed |

#### Returns

a new TpSimpleHandler.

#### Parameters

factory | a TpSimpleClientFactory, which may not be `NULL` |
bypass_approval | the value of the Handler.BypassApproval D-Bus property (see `tp_base_client_set_handler_bypass_approval()` for details) |
