Detailed Description

Macro Definition Documentation

◆ ELDBUS_ARGS

#define ELDBUS_ARGS ( args... ) (const Eldbus_Arg_Info[]){ args, { NULL, NULL } }

Used to insert complete types to signature of methods or signals.

Example: ELDBUS_ARGS({"s", "interface"}, {"s", "property"}) The signature will be "ss" and each string will have a tag name on introspect XML with the respective name.

Examples: complex-types-server.c, server.c, and simple-signal-emit.c.

Typedef Documentation

◆ Eldbus_Property_Get_Cb

typedef Eina_Bool(* Eldbus_Property_Get_Cb) (const Eldbus_Service_Interface *iface, const char *propname, Eldbus_Message_Iter *iter, const Eldbus_Message *request_msg, Eldbus_Message **error)

Callback function to append property value to message.

Parameters

iface	interface of property
propname	name of property
iter	variant iterator in which value must be appended
request_msg	message that request property
error	if a error happen you must set a message error to be send caller

Returns: EINA_TRUE if success

Note: request_msg and error arguments are only different from NULL when a client request a property with Properties.Get or Properties.GetAll. Upon calls to eldbus_service_property_changed(), this callback will also be called. It's a mistake to return an error in this case because if a property changed, it must have a new value set and it should be able to be read.

◆ Eldbus_Property_Set_Cb

typedef Eldbus_Message *(* Eldbus_Property_Set_Cb) (const Eldbus_Service_Interface *iface, const char *propname, Eldbus_Message_Iter *iter, const Eldbus_Message *input_msg)

Callback function to set property value from message.

Parameters

iface	interface of property
propname	name of property
input_msg	message call where you have to get value

Returns: Message of response, could be a simple method_return, error or NULL to send response later.

◆ eldbus_service_interface_unregister()

void eldbus_service_interface_unregister ( Eldbus_Service_Interface * iface )

Unregister a interface.

Note: This doesn't unregister the object path if interface count reaches 0. Use eldbus_service_object_unregister() to unregister the object.

Parameters

iface interface to unregister

References eina_hash_del(), and EINA_TRUE.

◆ eldbus_service_object_unregister()

void eldbus_service_object_unregister ( Eldbus_Service_Interface * iface )

Unregister all interfaces of the object path that this interface belongs and the object path.

Parameters

iface interface to unregister

	)

Emit a signal handler of the interface with non-complex types.

Each signal handler have a internal id, the first signal handler of interface is = 0 the second = 1 and go on.

Parameters

iface	interface of the signal
signal_id	id of signal
...	values that will be send on signal

Returns: EINA_TRUE if success
