+ 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.

+
+ 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.

+This is corrected from Chun Lee's explanation in an email at:

+
+1-> a double variable UNITBIT32 is assigned to 1572864. This is what it
+looks like in memory in a little endian machine:
+byte 7 byte 6 byte 5 byte 4 byte 3 byte 2 byte 1 byte 0
+00000000 00000000 00000000 00000000 00000000 00000000 0001 1100 1000001 0
+|<------fraction------------------>|<----1572864--------->|exponent |sign|
+
+The reason for 1572864 (1.5 X 2^20) is that its representation in IEEE754 format (double)
+has 51 zeros to the right of a placeholding 1 bit, which can then be used as
+a wide fixed-point register with the binary point at bit 32, so the lower 32 bits
+can be used as a fractional accumulator with 32-bit precision.
+Adding 1 to INITBIT32 adds a 1 at bit 32, with no change in exponent,
+so the lower 32 bits act as a fraction of one. The 31 zero bits in the integer part
+can be set as high as 2147483647 (31 1s) without affecting the precision.
+
+The upper 32 bits are 1094189056, or 01000001 00111000 00000000 00000000 in binary.
+The sign bit is zero, or positive. The upper bit of the exponent is one, meaning
+the number is normalized, or full precision.The exponent is 1043 minus the bias
+of 1023, or 20.
+
+This is the representation of the number 1.5 X 2^20 = 1572864:
+
+IEEE Standard 754 Double Precision Storage Format (double):
+63 62 52 51 32 31 0
++--------+----------------+-------------------+------------------------------+
+| s 1bit | e[62:52] 11bit | f[51:32] 20bit | f[31:0] 32bit |
++--------+----------------+-------------------+------------------------------+
+B0-------------->B1---------->B2----->B3----->B4----->B5----->B6----->B7----->
+0 10000010011 1000000000000000000000000000000000000000000000000000
+
+2-> there is the tabfudge like:
+
+Union tabfudge
+{
+ double tf_d;
+ int32 tf_i[2];
+}
+
+In dsp_perfrom:
+
+Union tabfudge tf;
+
+tf.tf_d = UNITBIT32;
+
+3-> the phase is accumulated into tf_d plus the UNITBIT32
+
+Double dphase = x_phase + UNITBIT32;
+
+4-> byte 0 to byte 3 is stored as a separate variable as:
+
+int normhipart = tf.tf_I[HIOFFSET]; //where HIOFFSET is used to find MSB
+
+5-> in the actual dsp block, although the phase is accumulated into
+tf.tf_d, bytes 0 to 3 of tf.tf_d are constantly forced to be a
+constant by:
+
+tf.tf_i[HIOFFSET] = normhipart;
+
+6-> because of this, to get the fraction part out of the tf.tf_d, simply do:
+
+tf.tf_d - UNITBIT32;
+
+7-> mission accomplished!!!!!
