Function Documentation

ectty_create()

ec_tty_t* ectty_create	(	const ec_tty_operations_t *	ops,
		void *	cb_data
	)

Create a virtual TTY interface.

Parameters

ops	Set of callbacks.
cb_data	Arbitrary data, that is passed to any callback.

Returns

Pointer to the interface object, otherwise an ERR_PTR value.

ectty_free()

void ectty_free

(

ec_tty_t *

tty

)

Releases a virtual TTY interface.

Parameters

tty	TTY interface.

ectty_tx_data()

unsigned int ectty_tx_data	(	ec_tty_t *	tty,
		uint8_t *	buffer,
		size_t	size
	)

Reads data to send from the TTY interface.

If there are data to send, they are copied into the buffer. At maximum, size bytes are copied. The actual number of bytes copied is returned.

Returns

Number of bytes copied.

Parameters

tty	TTY interface.
buffer	Buffer for data to transmit.
size	Available space in buffer.

ectty_rx_data()

void ectty_rx_data	(	ec_tty_t *	tty,
		const uint8_t *	buffer,
		size_t	size
	)

Pushes received data to the TTY interface.

Parameters

tty	TTY interface.
buffer	Buffer with received data.
size	Number of bytes in buffer.
