  /* 

     dumpOSC.c
	server that displays OpenSoundControl messages sent to it
	for debugging client udp and UNIX protocol

     by Matt Wright, 6/3/97
       modified from dumpSC.c, by Matt Wright and Adrian Freed

     version 0.2: Added "-silent" option a.k.a. "-quiet"

     version 0.3: Incorporated patches from Nicola Bernardini to make
       things Linux-friendly.  Also added ntohl() in the right places
       to support little-endian architectures.
 


	compile:
		cc -o dumpOSC dumpOSC.c

	to-do:

	    More robustness in saying exactly what's wrong with ill-formed
	    messages.  (If they don't make sense, show exactly what was
	    received.)

	    Time-based features: print time-received for each packet

	    Clean up to separate OSC parsing code from socket/select stuff

	pd: branched from http://www.cnmat.berkeley.edu/OpenSoundControl/src/dumpOSC/dumpOSC.c
	-------------
	-- added pd functions
	-- socket is made differently than original via pd mechanisms
	-- tweaks for Win32    www.zeggz.com/raf	13-April-2002
	-- the OSX changes from cnmat didnt make it here yet but this compiles
	   on OSX anyway.
