#define _CFFI_

/* We try to define Py_LIMITED_API before including Python.h.

   Mess: we can only define it if Py_DEBUG, Py_TRACE_REFS and
   Py_REF_DEBUG are not defined.  This is a best-effort approximation:
   we can learn about Py_DEBUG from pyconfig.h, but it is unclear if
   the same works for the other two macros.  Py_DEBUG implies them,
   but not the other way around.

   The implementation is messy (issue #350): on Windows, with _MSC_VER,
   we have to define Py_LIMITED_API even before including pyconfig.h.
   In that case, we guess what pyconfig.h will do to the macros above,
   and check our guess after the #include.

   Note that on Windows, with CPython 3.x, you need >= 3.5 and virtualenv
   version >= 16.0.0.  With older versions of either, you don't get a
   copy of PYTHON3.DLL in the virtualenv.  We can't check the version of
   CPython *before* we even include pyconfig.h.  ffi.set_source() puts
   a ``#define _CFFI_NO_LIMITED_API'' at the start of this file if it is
   running on Windows < 3.5, as an attempt at fixing it, but that's
   arguably wrong because it may not be the target version of Python.
   Still better than nothing I guess.  As another workaround, you can
   remove the definition of Py_LIMITED_API here.

   See also 'py_limited_api' in cffi/setuptools_ext.py.

/*
 * linear2ulaw() accepts a 14-bit signed integer and encodes it as u-law data
 * stored in a unsigned char.  This function should only be called with
 * the data shifted such that it only contains information in the lower
 * 14-bits.
 *
 * In order to simplify the encoding process, the original linear magnitude
 * is biased by adding 33 which shifts the encoding range from (0 - 8158) to
 * (33 - 8191). The result can be seen in the following encoding table:
 *
 *      Biased Linear Input Code        Compressed Code
 *      ------------------------        ---------------
 *      00000001wxyza                   000wxyz
 *      0000001wxyzab                   001wxyz
 *      000001wxyzabc                   010wxyz
 *      00001wxyzabcd                   011wxyz
 *      0001wxyzabcde                   100wxyz
 *      001wxyzabcdef                   101wxyz
 *      01wxyzabcdefg                   110wxyz
 *      1wxyzabcdefgh                   111wxyz
 *
 * Each biased linear code has a leading 1 which identifies the segment
 * number. The value of the segment number is equal to 7 minus the number
 * of leading 0's. The quantization interval is directly available as the
 * four bits wxyz.  * The trailing bits (a - h) are ignored.
 *
 * Ordinarily the complement of the resulting code word is used for
 * transmission, and so the code word is complemented before it is returned.
 *
 * For further information see John C. Bellamy's Digital Telephony, 1982,
 * John Wiley & Sons, pps 98-111 and 472-476.
