/*
*+
*  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
