C     ------------------
C
C     PFIELD     - Array containing regular grid data.
C
C
C     Method.
C     -------
C
C     Data is interpolated and expanded into a temporary array,
C     which is then copied back into the user's array.
C     Returns an error code if an invalid interpolation is requested
C     or field size exceeds array dimensions.
C
C     Comments.
C     ---------
C
C     This routine is an adaptation of QU2REG to allow missing data
C     values, and hence bit mapped fields.

C**** QU2REG3 - Convert quasi-regular grid data to regular.
C
C     Purpose.
C     --------
C
C     Convert quasi-regular grid data to regular,
C     using either a linear or cubic interpolation.
C
C
C**   Interface.
C     ----------
C
C     CALL QU2REG3(PFIELD,KPOINT,KLAT,KLON,KCODE,PMSVAL,OMISNG,OPERIO,
C    X            OVEGGY)
C
C
C     Input Parameters.
C     -----------------
C
C     PFIELD     - Array containing quasi-regular grid data.
C
C     KPOINT     - Array containing list of the number of
C                  points on each latitude (or longitude) of
C                  the quasi-regular grid.
C
C     KLAT       - Number of latitude lines
C
C     KLON       - Number of longitude lines
C
C     KCODE      - Interpolation required.
C                  1 , linear - data quasi-regular on latitude lines.
C                  3 , cubic -  data quasi-regular on latitude lines.
C                  11, linear - data quasi-regular on longitude lines.
C                  13, cubic -  data quasi-regular on longitude lines.
C
C     PMSVAL     - Value used for missing data indicator.
C
C     OMISNG     - True if missing values are present in field.
C
C     OPERIO     - True if input field is periodic.
C
C     OVEGGY     - True if 'nearest neighbour' processing must be used
C                  for interpolation
C
C
C     Output Parameters.
C     ------------------
C
C     KRET       - return code
C                  0 = OK
C                  non-zero indicates fatal error
C
C
C     Output Parameters.
C     ------------------
C
C     PFIELD     - Array containing regular grid data.
C
C
C     Method.
C     -------
C
C     Data is interpolated and expanded into a temporary array,
C     which is then copied back into the user's array.
C     Returns an error code if an invalid interpolation is requested
C     or field size exceeds array dimensions.
C
C     Comments.
C     ---------
C
C     This routine is an adaptation of QU2REG to allow missing data
C     values, and hence bit mapped fields.

    In GRIB edition 1, the edition number is in octet 8.
    In GRIB edition 0, octet 8 is reserved and set to 0.
    In GRIB edition -1, octet 8 is a flag field and can have a
    a valid value of 0, 1, 2 or 3.

    However, GRIB edition number 0 has a fixed
    length of 24, included in the message, for section 1, so
    if the value extracted from octets 5-7 is 24 and that from

This is a base class for all objects that need reference counting.
A CdiReferencedObject has a reference count of one when it is constructed, refObjectRetain() increments the reference count, refObject Release() decrements it.
When the reference count reaches zero, the destructor function is called before the memory of the object is deallocated with Free().

>>> Warning <<<
This code is currently not thread-safe.

We are currently using the C99 standard, which does not have atomic types.
Also, there are still tons of systems out there that have a gcc without wrong C11 atomics support
(__STDC_NO_ATOMICS__ not defined even though stdatomics.h is not even present).
Consequently, it is impossible to write preprocessor code to even check for the presence of atomic types.
So, we have two options: provide multithreading support by means of locks, or wait a year or two before doing this right.
I, for one, prefer doing things right.

class CdiIterator

An iterator is an object that identifies the position of one record in a file, where a record is defined as the data belonging to one level, timestep, and variable.
Using iterators to read a file can be significantly faster than using streams, because they can avoid building an index of the file.
For file formats like grib that do not provide an index within the file, this makes the difference between reading the file once or reading the file twice.

CdiIterator is an abstract base class. Which derived class is used depends on the type of the file. The class hierarchy currently looks like this:

    CdiIterator <|--+-- CdiFallbackIterator
                    |
                    +-- CdiGribIterator

The fallback implementation currently uses the stream interface of CDI under the hood to provide full functionality for all filetypes for which no iterator implementation exists yet.

@Function cdiIterator_inqVTime
@Title Get the validity time of the current field

@Prototype char* cdiIterator_inqVTime(CdiIterator* me)
@Parameter
    @item iterator The iterator to operate on.

@Result A malloc'ed string containing the validity time of the current field in the format "YYYY-MM-DDTHH:MM:SS.mmm".

@Description
The returned time is the validity time as it is returned by taxisInqVtime(), only more precise.
That is, if the field is a time point, its time is returned,
if it is a statistical field with an integration period, the end time of the integration period is returned.

Converts the time to the ISO-8601 format and returns it in a newly allocated buffer.
The caller is responsible to Free() the resulting string.

If the file is a GRIB file, the calendar that is used to resolve the relative times is the proleptic calendar
as it is implemented by the standard C mktime() function.
This is due to the fact that GRIB-API version 1.12.3 still does not implement the calendar identification fields.

   Modifications:
      Oct 1997: Changed symbol name extname to appendus (PDW/HSTX)
                (Conflicted with a common variable name in FTOOLS)
      Nov 1997: If g77Fortran defined, also define f2cFortran (PDW/HSTX)
      Feb 1998: Let VMS see the NUM_ELEMS code. Lets programs treat
                single strings as vectors with single elements
      Nov 1999: If macintoxh defined, also define f2cfortran (for Mac OS-X)
      Apr 2000: If WIN32 defined, also define PowerStationFortran and
                VISUAL_CPLUSPLUS (Visual C++)
      Jun 2000: If __GNUC__ and linux defined, also define f2cFortran
                (linux/gcc environment detection)
      Apr 2002: If __CYGWIN__ is defined, also define f2cFortran
      Nov 2002: If __APPLE__ defined, also define f2cfortran (for Mac OS-X)

      Nov 2003: If __INTEL_COMPILER or INTEL_COMPILER defined, also define
                f2cFortran (KMCCARTY)
      Dec 2005: If f2cFortran is defined, enforce REAL functions in FORTRAN
                returning "double" in C.  This was one of the items on
		Burkhard's TODO list. (KMCCARTY)
      Dec 2005: Modifications to support 8-byte integers. (MR)
		USE AT YOUR OWN RISK!
      Feb 2006  Added logic to typedef the symbol 'LONGLONG' to an appropriate
                intrinsic 8-byte integer datatype  (WDP)
      Apr 2006: Modifications to support gfortran (and g77 with -fno-f2c flag)
                since by default it returns "float" for FORTRAN REAL function.
                (KMCCARTY)
      May 2008: Revert commenting out of "extern" in COMMON_BLOCK_DEF macro.
		Add braces around do-nothing ";" in 3 empty while blocks to
		get rid of compiler warnings.  Thanks to ROOT developers
		Jacek Holeczek and Rene Brun for these suggestions. (KMCCARTY)
      Aug 2008: If __GNUC__ is defined and no FORTRAN compiler is specified
		via a #define or -D, default to gfortran behavior rather than
		g77 behavior. (KMCCARTY)
      Oct 2009: Add warning if guessing default fortran. Move g77 above guessing bloc
