+/*
+*+
+*  Name:
+*     f77.h and cnf.h
+
+*  Purpose:
+*     C - FORTRAN interace macros and prototypes
+
+*  Language:
+*     C (part ANSI, part not)
+
+*  Type of Module:
+*     C include file
+
+*  Description:
+*     For historical reasons two files, F77.h and cnf.h are required
+*     but the have now been combined and for new code, only one is
+*     necessary.
+*
+*     This file defines the macros needed to write C functions that are
+*     designed to be called from FORTRAN programs, and to do so in a
+*     portable way. Arguments are normally passed by reference from a
+*     FORTRAN program, and so the F77 macros arrange for a pointer to
+*     all arguments to be available. This requires no work on most
+*     machines, but will actually generate the pointers on a machine
+*     that passes FORTRAN arguments by value.
+
+*  Notes:
+*     -  Macros are provided to handle the conversion of logical data
+*        values between the way that FORTRAN represents a value and the
+*        way that C represents it.
+*     -  Macros are provided to convert variables between the FORTRAN and
+*        C method of representing them. In most cases there is no
+*        conversion required, the macros just arrange for a pointer to
+*        the FORTRAN variable to be set appropriately. The possibility that
+*        FORTRAN and C might use different ways of representing integer
+*        and floating point values is considered remote, the macros are
+*        really only there for completeness and to assist in the automatic
+*        generation of C interfaces.
+*     -  For character variables the macros convert between
+*        the FORTRAN method of representing them (fixed length, blank
+*        filled strings) and the C method (variable length, null
+*        terminated strings) using calls to the CNF functions.
+
+*  Implementation Deficiencies:
+*     -  The macros support the K&R style of function definition, but
+*        this file may not work with all K&R compilers as it contains
+*        "#if defined" statements. These could be replaced with #ifdef's
+*        if necessary. This has not been done as is would make the code
+*        less clear and the need for support for K&R sytle definitions
+*        should disappear as ANSI compilers become the default.

+
+*  History:
+*     23-MAY-1991 (PMA):
+*        Original version.
+*     19-JUN-1991 (PMA):
+*        Removed VMS versions of IM(EX)PORT_LOGICAL macros that tried
+*        to convert data representations.
+*     24-JUN-1991 (PMA):
+*        Changed the names of IMPORT macros to GENPTR.
+*        Removed the EXPORT macros.
+*     27-JUN-1991 (PMA):
+*        Modified DECstation specific stuff to allow use of the c89
+*        compiler.
+*      8-JUL-1991 (PMA):
+*        Added macros to call FORTRAN from C.
+*     16-OCT-1991 (PMA):
+*        Remove type_ARRAY2 definitions.
+*        Remove the length argument from CHARACTER_ARRAY and the
+*        dimension specifier from GENPTR_type_ARRAY.
+*        Add extra brackets to F77_ISFALSE and F77_ISTRUE.
+*     25-OCT-1991 (PMA):
+*        Changed "if defined(sun4)" to "if defined(sun)"
+*     2-JUN-1992 (PMA):
+*        Changed "if defined(mips)" to "if defined(ultrix)" to prevent
+*        those definitions being used on a Silicon Graphics machine.
+*     11-JUN-1992 (PMA):
+*        Changed "if defined(ultrix)" back to "if defined(mips)" so that
+*        it still works on OSF/1 on a DECstation.
+*        Add support for general non-ANSI compilers, but not basic K&R
+*        ones.
+*     12-JUN-1992 (PMA):
+*        Change declaration of dummy scalar arguments to be const
+*        pointers.  Change declaration of dummy array arguments to be
+*        const pointers.
+*     5-JAN-1993 (PMA):
+*        Changed "if defined(mips)" so that it will recognise a
+*        DECstation running Ultrix or OSF/1, but not a Silicon Graphics
+*        workstation.
+*        Change the definition of F77_BYTE_TYPE to add "signed".
+*        Redefine this on VMS where signed is invalid syntax.
+*        Add new types of UBYTE and UWORD.
+*     8-JAN-1993 (PMA):
+*        Fix bug in the definition of CHARACTER_RETURN_VALUE. There was
+*        an extraneous space.
+*        Add a macro F77_POINTER_TYPE and use it to define POINTER.
+*     13-JAN-1993 (PMA):
+*        Start to add support for K&R function definitions. These are
+*        done on a per machine basis.
+*     16-APR-1993 (PMA):
+*        Change the definition of F77_POINTER_TYPE from int to unsigned
+*        int.
+*     7-MAY-1993 (PMA):
+*        Change from using a null comment as a token concatenation
+*        operator to using the internal macro _f77_x on non-ANSI
+*        systems.
+*     10-MAY-1993 (PMA):
+*        Finish adding K&R support. This will form version 2.0 of F77.
+*     10-MAY-1993 (PMA):
+*        Add support for Alpha OSF/1.
+*     9-JUL-1993 (PMA):
+*        Add further POINTER macros: POINTER_ARRAY,
+*        GENPTR_POINTER_ARRAY, DECLARE_POINTER, DECLARE_POINTER_ARRAY,
+*        POINTER_ARG, POINTER_ARRAY_ARG, F77_POINTER_FUNCTION,
+*        KR_POINTER_ARRAY.
+*     24-AUG-1993 (PMA):
+*        Add const to the VMS definitions of CHARACTER and CHARACTER_ARRAY.
+*     3-NOV-1993 (PMA):
+*        Remove K&R stuff to a separate file.
+*        Released on Unix as version 2.0 of CNF.
+*     11-NOV-1993 (PMA):
+*        Return to using the null comment to concatenate text on non-ANSI
+*        systems as _f77_x caused problems with the c89 -common flag on
+*        DECstations.
+*     23-JAN-1996 (AJC):
+*        Add SUBROUTINE, type_FUNCTION, SUBROUTINE_ARG,
+*        type_FUNCTION_ARG, GENPTR_SUBROUTINE and GENPTR_type_FUNCTION
+*        required for passed subroutine and function name.
+*     29-JAN-1996 (AJC):
+*        Add the dynamic CHARACTER_ macros
+*        and CHARACTER_ARG_TYPE
+*     22-FEB-1996 (AJC):
+*        Add CHARACTER_RETURN_ARG
+*     23-MAY-1996 (AJC):
+*        Add DECLARE_CHARACTER_ARRAY_DYN
+*            F77_CREATE_CHARACTER_ARRAY
+*            F77_CHARACTER_ARG_TYPE
+*     14-JUN-1996 (AJC):
+*        Add DECLARE_LOGICAL_ARRAY_DYN
+*            F77_CREATE_LOGICAL_ARRAY
+*     21-JUN-1996 (AJC):
+*        Add cast to _ARRAY_ARGs to allow multidimensional arrays
+*     17-MAR-1998 (AJC):
+*        Add DECLARE, CREATE and FREE dynamic array macros for all types
+*        Changed CREATE_CHARACTER_ARRAY and CREATE_LOGICAL_ARRAY to use
+*         number of elements rather than dimensions.
+*        Add IMPORT, EXPORT and ASSOC macros
+*     22-JUL-1998 (AJC):
+*        Combined F77.h and cnf.h
+*     23-SEP-1998 (AJC):
+*        Input strings for cnf -> const char *
+*        Input int arrays for cnf -> const int *
+*      4-NOV-1998 (AJC):
+*        Bring cnf prototypes in line with .c routines
+*      8-FEB-1999 (AJC):
+*        Added cnf_mem stuff
+*      9-FEB-1999 (AJC):
+*        Use cnf_cptr/fptr for IMPORT/EXPORT_POINTER
+*     16-FEB-1999 (AJC):
+*        Added missing cnf_fptr prototype
+*     23-JUN-1999 (AJC):
+*        Change cnf_name to cnfName
+*        and add macros for cnf_name
+*      1-DEC-1999 (AJC):
+*        Add define cnf_free
+*      7-JAN-2000 (AJC):
+*        Correct omission of F77_ASSOC_UBYTE_ARRAY
+*        Correct F77_EXPORT_UWORD_ARRAY
+*      25-AUG-2005 (TIMJ):
+*        Add cnfInitRTL
+*      23-FEB-2006 (TIMJ):
+*        Add cnfRealloc
+*        Use starMalloc rather than malloc in F77_CREATE_POINTER_ARRAY
+*        (since it needs to match what goes on in cnfFree)
+*      21-JUN-2006 (PWD):
+*        Changed to use a different return type for REAL functions. This
+*        effects g77 under 64-bit, when the f2c bindings expect the return
+*        value of a REAL function to be a double, not a float.
+*      25-SEP-2006 (PWD):
+*        Introduced F77_CREATE_IMPORT_CHARACTER. Match length of
+*        F77_CREATE_CHARACTER to result from cnfCref.
+*      13-JUL-2007 (PWD):
+*        Parameterise the type of Fortran character string lengths. Can
+*        be long.
+*      7-OCT-2008 (TIMJ):
+*        Initialise pointers.
+*      11-MAY-2011 (DSB):
+*        Added F77_LOCK
