Function Documentation

ec_eoe_init()

int ec_eoe_init	(	ec_eoe_t *	eoe,
		ec_slave_t *	slave
	)

EoE constructor.

Initializes the EoE handler, creates a net_device and registers it.

Returns

Zero on success, otherwise a negative error code.

Parameters

eoe	EoE handler
slave	EtherCAT slave

Definition at line 111 of file ethernet.c.

ec_eoe_clear()

void ec_eoe_clear

(

ec_eoe_t *

eoe

)

EoE destructor.

Unregisteres the net_device and frees allocated memory.

Parameters

eoe	EoE handler

Definition at line 223 of file ethernet.c.

ec_eoe_is_open()

int ec_eoe_is_open

(

const ec_eoe_t *

eoe

)

Returns the state of the device.

Returns

1 if the device is "up", 0 if it is "down"

Parameters

eoe	EoE handler

Definition at line 385 of file ethernet.c.

ec_eoe_is_idle()

int ec_eoe_is_idle

(

const ec_eoe_t *

eoe

)

Returns the idle state.

Return values

1	The device is idle.
0	The device is busy.

Parameters

eoe	EoE handler
