Functions
static void	duds::hardware::interface::linux::AddOffset (gpiohandle_request &req, std::uint32_t offset)
	Adds a GPIO line offset to a gpiohandle_request object. More...
static void	duds::hardware::interface::linux::CloseIfOpen (gpiohandle_request &req)
	Closes the file descriptor in the request object if it appears to have a file, and then sets the descriptor to zero. More...
static int	duds::hardware::interface::linux::FindOffset (gpiohandle_request &req, std::uint32_t offset)
	Finds the array index that corresponds to the given offset. More...
static void	duds::hardware::interface::linux::GetInput (int chipFd, gpiohandle_data &result, gpiohandle_request &req)
	Requests input states from the kernel. More...
static void	duds::hardware::interface::linux::InitGpioHandleReq (gpiohandle_request &req, const std::string &consumer)
	Initializes a gpiohandle_request structure. More...
static bool	duds::hardware::interface::linux::RemoveOffset (gpiohandle_request &req, std::uint32_t offset)
	Removes a GPIO line offset from a gpiohandle_request object. More...
static void	duds::hardware::interface::linux::SetOutput (int chipFd, gpiohandle_request &req)
	Sets the output states for all the pins in the request object. More...
