Public Functions

Type	Name
int	get () const This is for quick access to the value, otherwise, it's recommended to keep the.
int	getOpts (upisnd_analog_input_opts_t & opts) const Retrieves the Analog Input options.
int	setOpts (const upisnd_analog_input_opts_t & opts) Sets the Analog Input options.
	Element ()
	Element (upisnd_element_ref_t el) Implicitly increments the refcount. If you got the element from C API, don't forget to unref it afterwards.
	Element (const Element & rhs)
	Element (Element && rhs)
	Element (upisnd_element_ref_t el, bool)

Type	Name
	Element ()
	Element (upisnd_element_ref_t el) Implicitly increments the refcount. If you got the element from C API, don't forget to unref it afterwards.

Element &	operator= (Element && rhs)
	~Element () Unreferences the element.
bool	isValid () const Checks if the element is valid.
void	release () Unreferences the underlying C upisnd_element_ref_t handle and resets the object.
const char *	getName () const Gets the name of the element.
upisnd_element_type_e	getType () const Gets the type of the element.
upisnd_pin_t	getPin () const Gets the pin of the element.
ValueFd	openValueFd (int flags) const Opens the Element 's value attribute as a file descriptor.
T	as () const Safely casts the element to the requested class. Returns an invalid object if the cast is not possible.

get

This is for quick access to the value, otherwise, it's recommended to keep the.

int upisnd::AnalogInput::get () const

ValueFd returned by Element::openValueFd, to avoid file open and close overhead. Inspect the errno to check for errors.

    upisnd_analog_input_opts_t & opts
) const

setOpts

Sets the Analog Input options.
