I am not using yours as your code sends the three file sequentially, but the required output sends three columns in a row, one at a time. That's why I concatenate three lines into one.
Code:
Connected to server!  
Data returned by the server:  
TEMPERATURE = 60 HUMIDITY = 40 LIGHT = 1  
Data returned by the server:  
TEMPERATURE = 59 HUMIDITY = 50 LIGHT = 2  
Data returned by the server:  
TEMPERATURE = 58 HUMIDITY = 20 LIGHT = 3

Your code sends the files one after another.
If I treat the three items (temperature, light, humidity) as a single intact record, then your output seems different from the sample output format, whereas my way seems to be what is required, except the following problems:
1)The whole dataset is output all at once, instead of individual record (3 numbers in a row);
2)The whole dataset is output in the way of 1) 30 times in total (which is exactly the total record numbers), that's what should be fixed.
Not sure if I missed some of your points. Thanks.

roar_simple_stream(3)					System Manager's Manual: RoarAudio				     roar_simple_stream(3)

NAME

       roar_simple_stream - Opens a stream to RoarAudio's sound server

SYNOPSIS

       #include <roaraudio.h>

       int roar_simple_stream(int rate, int channels, int bits, int codec, char * server, int dir, char * name);

DESCRIPTION

       This  creates a new stream to RoarAudio. Normally you want to use one of roar_simple_play(3), roar_simple_monitor(3), roar_simple_record(3)
       or roar_simple_filter(3).

       his functions are marked obsolete and will be removed very soon.  Please upgrade to VS API. See roar_vs_new_simple(3).

PARAMETERS

       rate, channels, bits, codec, server, name
	      For an explanation on these parameters see roar_simple_play(3).

       dir    The direction of the new stream. See below for a list of valid directions.

STREAM DIRECTIONS

       ROAR_DIR_PLAY
	      This stream directions meens that a player streams data to the server in order to play it back.

       ROAR_DIR_RECORD
	      This direction is to record audio from the soundcard. This is used if for example you want to get data from your microphon  or  line
	      in.

       ROAR_DIR_MONITOR
	      This  direction  is  used  to get a copy of what the server sends to the soundcard. This can for example be used to stream the fully
	      mixed data to Icecast (see icecast2(1)).

       ROAR_DIR_FILTER
	      This is used to crate a filter stream: A filter stream is a stream used to filter the output of the sound server by some tool.  This
	      can  for	example be used for an software equalizer. The filter stream is the only bi-directional stream. You have to read some data
	      and write back data of exactly the same size.

       ROAR_DIR_OUTPUT
	      This is the type of the stream the server sends to the soundcard. You can not create such a stream. It's only listend for  complete-
	      ness.

RETURN VALUE

       On success these calls return a filehandle.  On error, -1 is returned.

EXAMPLES

       FIXME
