Function Documentation

fetch_ext_or_command_from_buf()

int fetch_ext_or_command_from_buf	(	buf_t *	buf,
		ext_or_cmd_t **	out )

Read buf, which should contain an Extended ORPort message from a transport proxy. If well-formed, create and populate out with the Extended ORport message. Return 0 if the buffer was incomplete, 1 if it was well-formed and -1 if we encountered an error while parsing it.
