Signature of the implementation of the AddDispatchOperation method.

This function must call either `tp_add_dispatch_operation_context_accept()`, `tp_add_dispatch_operation_context_delay()` or `tp_add_dispatch_operation_context_fail()` on `context` before it returns.

`approver` : | a TpSimpleApprover 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. [element-type TelepathyGLib.Channel]
`dispatch_operation` : | a TpChannelDispatchOperation or `NULL`; the dispatch_operation is not guaranteed to be prepared. [allow-none]
`context` : | a TpAddDispatchOperationContext representing the context of this D-Bus call
`user_data` : | arbitrary user-supplied data passed to `tp_simple_approver_new()`

Since 0.11.5

### tp_simple_approver_new ()

    TpBaseClient *      tp_simple_approver_new              (TpDBusDaemon *dbus,
                                                             const gchar *name,

                                                             TpSimpleApproverAddDispatchOperationImpl callback,
                                                             gpointer user_data,

### Warning

`tp_simple_approver_new` is deprecated and should not be used in newly-written code. New code should use `tp_simple_approver_new_with_am()` instead.

Convenient function to create a new TpSimpleApprover instance.

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

`dbus` : | a TpDBusDaemon object, may not be `NULL`
`name` : | the name of the Approver (see "name" for details)
`uniquify` : | the value of the "uniquify-name" property
`callback` : | the function called when AddDispatchOperation is called
`user_data` : | arbitrary user-supplied data passed to `callback`
`destroy` : | called with `user_data` as its argument when the TpSimpleApprover is destroyed
Returns : | a new TpSimpleApprover. [type TelepathyGLib.SimpleApprover]

Since 0.11.5

### tp_simple_approver_new_with_am ()

    TpBaseClient *      tp_simple_approver_new_with_am      (TpAccountManager *account_manager,

                                                             gboolean uniquify,

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

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

`account_manager` : | an account manager, which may not be `NULL`
`name` : | the name of the Approver (see "name" for details)
`uniquify` : | the value of the "uniquify-name" property
`callback` : | the function called when AddDispatchOperation is called
`user_data` : | arbitrary user-supplied data passed to `callback`
`destroy` : | called with `user_data` as its argument when the TpSimpleApprover is destroyed
Returns : | a new TpSimpleApprover. [type TelepathyGLib.SimpleApprover]
