Add FS #10214. Initial commit of the original PDa code for the GSoC Pure Data plugin project of Wincent Balin. Stripped some non-sourcefiles and added a rockbox readme that needs a bit more info from Wincent. Is added to CATEGORIES and viewers, but not yet to SUBDIRS (ie doesn't build yet)

31 dumpOSC.c
32 server that displays OpenSoundControl messages sent to it
33 for debugging client udp and UNIX protocol
34
35 by Matt Wright, 6/3/97
36 modified from dumpSC.c, by Matt Wright and Adrian Freed
37
38 version 0.2: Added "-silent" option a.k.a. "-quiet"
39
40 version 0.3: Incorporated patches from Nicola Bernardini to make
41 things Linux-friendly. Also added ntohl() in the right places
42 to support little-endian architectures.
43
44
45
46 compile:
47 cc -o dumpOSC dumpOSC.c
48
49 to-do:
50
51 More robustness in saying exactly what's wrong with ill-formed
52 messages. (If they don't make sense, show exactly what was
53 received.)
54
55 Time-based features: print time-received for each packet
56
57 Clean up to separate OSC parsing code from socket/select stuff
58
59 pd: branched from http://www.cnmat.berkeley.edu/OpenSoundControl/src/dumpOSC/dumpOSC.c
60 -------------
61 -- added pd functions
62 -- socket is made differently than original via pd mechanisms
63 -- tweaks for Win32 www.zeggz.com/raf 13-April-2002
64 -- the OSX changes from cnmat didnt make it here yet but this compiles
65 on OSX anyway.

1030 dumpOSC.c
1031 server that displays OpenSoundControl messages sent to it
1032 for debugging client udp and UNIX protocol
1033
1034 by Matt Wright, 6/3/97
1035 modified from dumpSC.c, by Matt Wright and Adrian Freed
1036
1037 version 0.2: Added "-silent" option a.k.a. "-quiet"
1038
1039 version 0.3: Incorporated patches from Nicola Bernardini to make
1040 things Linux-friendly. Also added ntohl() in the right places
1041 to support little-endian architectures.
1042
1043
1044
1045 compile:
1046 cc -o dumpOSC dumpOSC.c
1047
1048 to-do:
1049
1050 More robustness in saying exactly what's wrong with ill-formed
1051 messages. (If they don't make sense, show exactly what was
1052 received.)
1053
1054 Time-based features: print time-received for each packet
1055
1056 Clean up to separate OSC parsing code from socket/select stuff
1057
1058 pd: branched from http://www.cnmat.berkeley.edu/OpenSoundControl/src/dumpOSC/dumpOSC.c
1059 -------------
1060 -- added pd functions
1061 -- socket is made differently than original via pd mechanisms
1062 -- tweaks for Win32 www.zeggz.com/raf 13-April-2002
1063 -- the OSX changes from cnmat didnt make it here yet but this compiles
1064 on OSX anyway.
