gn_gpio_fastcreate()

gn_leaf_handle_t gn_gpio_fastcreate	(	gn_node_handle_t	node,
		const char *	leaf_name,
		int	gpio,
		bool	inverted,
		bool	toggled
	)

creates a GPIO leaf defining all parameters

Parameters

node	the parent node
leaf_name	the name of the leaf to be created
gpio	the GPIO number to attach this leaf
inverted	if the GPIO need to work in inverted mode (toggle = true -> gpio = false)
toggled	the initial status

Returns

an handle to the leaf initialized

NULL in case of errors
