control_write_reply()

void control_write_reply	(	control_connection_t *	conn,
		int	code,
		int	c,
		const char *	s

read_escaped_data()

size_t read_escaped_data	(	const char *	data,
		size_t	len,
		char **	out
	)

Given a len-character string in data, made of lines terminated by CRLF, allocate a new string in *out, and copy the contents of data into *out, removing any period that appears at the start of a line, and replacing all CRLF sequences with LF. Return the number of bytes in *out.

This corresponds to CmdData in control-spec.txt.

Definition at line 130 of file control_proto.c.

send_control_done()

void send_control_done

(

control_connection_t *

conn

)

Send a "DONE" message down the control connection conn.

write_escaped_data()

size_t write_escaped_data	(	const char *	data,
		size_t	len,
		char **	out
	)

Given a len-character string in data, made of lines terminated by CRLF, allocate a new string in *out, and copy the contents of data into *out, adding a period before any period that appears at the start of a line, and adding a period-CRLF line at the end. Replace all LF characters sequences with CRLF. Return the number of bytes in *out.

This corresponds to CmdData in control-spec.txt.
