Function Documentation

telnet_cb_connected()

void telnet_cb_connected

(

sock_tcp_t *

sock

)

Callback function that gets called when a telnet client connects after stdio is redirected.

Parameters

[in]

sock

Socket of the client that just connected only use with sock_tcp_get_local

telnet_cb_pre_connected()

void telnet_cb_pre_connected

(

sock_tcp_t *

sock

)

Callback function that gets called when a telnet client connects but before stdio is redirected.

Parameters

[in]

sock

Socket of the client that just connected only use with sock_tcp_get_local

telnet_server_disconnect()

void telnet_server_disconnect

(

void

)

Request to disconnect the current client.

     This only sets the disconnect request flag, so it's safe to call
     this from interrupt context.

telnet_server_read()

int telnet_server_read	(	void *	buffer,
		size_t	count
	)

Read data from the telnet client, will block until data is available.

Parameters

[out]	buffer	The buffer to write data from the client
[in]	count	Number of bytes to read

Returns

number of bytes read, error otherwise

telnet_server_start()

int telnet_server_start

(

void

)

Start the Telnet server thread.

Returns

0 on success, error otherwise

telnet_server_write()

ssize_t telnet_server_write	(	const void *	buffer,
		size_t	len
	)

Write data to the telnet client.

Parameters

[in]	buffer	The buffer to send to the client
[in]	len	The length of the buffer

Returns

0 on success, error otherwise
