+ OSC-client.h: library for constructing OpenSoundControl messages.
+ Derived from SynthControl.h
+ Author: Matt Wright
+ Version 0.1: 6/13/97
+ Version 0.2: 7/21/2000: Support for type-tagged messages
+
+
+ General notes:
+
+ This library abstracts away the data format for the OpenSoundControl
+ protocol. Users of this library can construct OpenSoundControl packets
+ with a function call interface instead of knowing how to lay out the bits.
+
+ All issues of memory allocation are deferred to the user of this library.
+ There are two data structures that the user must allocate. The first
+ is the actual buffer that the message will be written into. This buffer
+ can be any size, but if it's too small there's a possibility that it
+ will become overfull. The other data structure is called an OSCbuf,
+ and it holds all the state used by the library as it's constructing
+ a buffer.
+
+ All procedures that have the possibility of an error condition return int,
+ with 0 indicating no error and nonzero indicating an error. The variable
+ OSC_errorMessage will be set to point to a string containing an error
+ message explaining what the problem is.
+
+*/
+/*
+ OSC_timeTag.h: library for manipulating OSC time tags
+ Matt Wright, 5/29/97
+
+ Time tags in OSC have the same format as in NTP: 64 bit fixed point, with the
+ top 32 bits giving number of seconds sinve midnight 1/1/1900 and the bottom
+ 32 bits giving fractional parts of a second. We represent this by an 8-byte
+ unsigned long if possible, or else a struct.
+
+ NB: On many architectures with 8-byte ints, it's illegal (like maybe a bus error)
+ to dereference a pointer to an 8 byte int that's not 8-byte aligned.

+ procedure will also leave space for the size count of this message.)
+ - Alternately, call OSC_writeAddressAndTypes() with the name of
+ your message and with a type string listing the types of all the

+ - Now write each of the arguments into the buffer, by calling one of:
+ OSC_writeFloatArg()
+ OSC_writeIntArg()
+ OSC_writeStringArg()
+ - Now your message is complete; you can send out the buffer or you can
+ add another message to it.

+
+ 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.
