Functions of class **afb_service**
==============================
All the functions of the class **afb_daemon** use the default api.
All these function are deprecated, try to use functions of class **afb_api** instead.
## afb_service_call
```C
/**
* @deprecated try to use @ref afb_api_call instead
*
* Calls the 'verb' of the 'api' with the arguments 'args' and 'verb' in the name of the binding.
* The result of the call is delivered to the 'callback' function with the 'callback_closure'.
*
* For convenience, the function calls 'json_object_put' for 'args'.
* Thus, in the case where 'args' should remain available after
* the function returns, the function 'json_object_get' shall be used.
*
* The 'callback' receives 5 arguments:
* 1. 'closure' the user defined closure pointer 'closure',
* 2. 'object' a JSON object returned (can be NULL)
* 3. 'error' a string not NULL in case of error but NULL on success
* 4. 'info' a string handling some info (can be NULL)
* 5. 'api' the api
*
* @param api The api name of the method to call
* @param verb The verb name of the method to call
* @param args The arguments to pass to the method
* @param callback The to call on completion
* @param closure The closure to pass to the callback
*
*
* @see afb_req_subcall
* @see afb_req_subcall_sync
* @see afb_api_call_sync

## afb_service_call_sync
```C
/**
* @deprecated try to use @ref afb_api_call_sync instead
*
* Calls the 'verb' of the 'api' with the arguments 'args' and 'verb' in the name of the binding.
* 'result' will receive the response.
*
* For convenience, the function calls 'json_object_put' for 'args'.
* Thus, in the case where 'args' should remain available after
* the function returns, the function 'json_object_get' shall be used.
*
* @param api The api name of the method to call
* @param verb The verb name of the method to call
* @param args The arguments to pass to the method
* @param object Where to store the returned object - should call json_object_put on it - can be NULL
* @param error Where to store the copied returned error - should call free on it - can be NULL
* @param info Where to store the copied returned info - should call free on it - can be NULL
*
* @returns 0 in case of success or a negative value in case of error.
*
* @see afb_req_subcall
