Detailed Description

This module provides functions for the gpioinfo protocol command.

Function Documentation

mygpio_gpioinfo()

bool mygpio_gpioinfo	(	struct t_mygpio_connection *	connection,
		unsigned	gpio )

Lists the current settings of a GPIO. Retrieve the settings with mygpio_recv_gpio_info and end the response with mygpio_response_end.

Parameters

connection	Pointer to the connection struct returned by mygpio_connection_new.
gpio	GPIO number

Returns

bool true on success, else false.

mygpio_recv_gpio_info()

struct t_mygpio_gpio * mygpio_recv_gpio_info

(

struct t_mygpio_connection *

connection

)

Receives the result of mygpio_gpioinfo. Free it with mygpio_free_gpio. Use the mygpio_gpio_get_gpio_*, mygpio_gpio_in_get_gpio_* and mygpio_gpio_in_get_gpio_* functions to access the values. The caller must free it with mygpio_free_gpio.

Parameters

connection

Pointer to the connection struct returned by mygpio_connection_new.

Returns

Allocated struct t_mygpio_gpio or NULL on list end or error.
