|
| +
|
| + A `LOGICAL(KIND=N)' variable is represented as an `INTEGER(KIND=N)'
|
| +variable, however, with only two permissible values: `1' for `.TRUE.'
|
| +and `0' for `.FALSE.'. Any other integer value results in undefined
|
| +behavior.
|
| +
|

|
| +`LOGICAL(KIND=C_BOOL)' variables which are interoperable with the C99
|
| +_Bool type. The C99 _Bool type has an internal representation
|
| +described in the C99 standard, which is identical to the above
|
| +description, i.e. with 1 for true and 0 for false being the only
|
| +permissible values. Thus the internal representation of `LOGICAL'
|
| +variables in GNU Fortran is identical to C99 _Bool, except for a
|
| +possible difference in storage size depending on the kind.

|
| +* Interoperable Subroutines and Functions::
|
| +
|
| + Since Fortran 2003 (ISO/IEC 1539-1:2004(E)) there is a standardized
|
| +way to generate procedure and derived-type declarations and global
|
| +variables which are interoperable with C (ISO/IEC 9899:1999). The
|
| +`bind(C)' attribute has been added to inform the compiler that a symbol
|
| +shall be interoperable with C; also, some constraints are added. Note,
|
| +however, that not all C features have a Fortran equivalent or vice
|
| +versa. For instance, neither C's unsigned integers nor C's functions
|
| +with variable number of arguments have an equivalent in Fortran.
|
| +
|
| + Note that array dimensions are reversely ordered in C and that
|
| +arrays in C always start with index 0 while in Fortran they start by
|
| +default with 1. Thus, an array declaration `A(n,m)' in Fortran matches
|
| +`A[m][n]' in C and accessing the element `A(i,j)' matches
|
| +`A[j-1][i-1]'. The element following `A(i,j)' (C: `A[j-1][i-1]';
|
| +assuming i < n) in memory is `A(i+1,j)' (C: `A[j-1][i]').

|
| +7.1.1 Intrinsic Types
|
| +---------------------
|
| +
|
| +In order to ensure that exactly the same variable type and kind is used
|
| +in C and Fortran, the named constants shall be used which are defined
|
| +in the `ISO_C_BINDING' intrinsic module. That module contains named
|
| +constants for kind parameters and character named constants for the
|
| +escape sequences in C. For a list of the constants, see *note
|

|
| +
|
| +7.1.2 Derived Types and struct
|
| +------------------------------
|
| +
|
| +For compatibility of derived types with `struct', one needs to use the
|
| +`BIND(C)' attribute in the type declaration. For instance, the
|
| +following type declaration
|
| +
|
| + USE ISO_C_BINDING
|
| + TYPE, BIND(C) :: myType
|
| + INTEGER(C_INT) :: i1, i2
|
| + INTEGER(C_SIGNED_CHAR) :: i3
|
| + REAL(C_DOUBLE) :: d1
|
| + COMPLEX(C_FLOAT_COMPLEX) :: c1
|
| + CHARACTER(KIND=C_CHAR) :: str(5)
|
| + END TYPE
|
| +
|
| + matches the following `struct' declaration in C
|
| +
|
| + struct {
|
| + int i1, i2;
|
| + /* Note: "char" might be signed or unsigned. */
|
| + signed char i3;
|
| + double d1;
|
| + float _Complex c1;
|
| + char str[5];
|
| + } myType;
|
| +
|
| + Derived types with the C binding attribute shall not have the
|
| +`sequence' attribute, type parameters, the `extends' attribute, nor
|
| +type-bound procedures. Every component must be of interoperable type
|
| +and kind and may not have the `pointer' or `allocatable' attribute. The
|
| +names of the variables are irrelevant for interoperability.
|
| +
|
| + As there exist no direct Fortran equivalents, neither unions nor
|
| +structs with bit field or variable-length array members are
|
| +interoperable.

|

|
| +7.1.3 Interoperable Global Variables
|
| +------------------------------------
|
| +
|
| +Variables can be made accessible from C using the C binding attribute,
|
| +optionally together with specifying a binding name. Those variables
|
| +have to be declared in the declaration part of a `MODULE', be of
|
| +interoperable type, and have neither the `pointer' nor the
|
| +`allocatable' attribute.
|
| +
|
| + MODULE m
|
| + USE myType_module
|
| + USE ISO_C_BINDING
|
| + integer(C_INT), bind(C, name="_MyProject_flags") :: global_flag
|
| + type(myType), bind(C) :: tp
|
| + END MODULE
|
| +
|
| + Here, `_MyProject_flags' is the case-sensitive name of the variable
|
| +as seen from C programs while `global_flag' is the case-insensitive
|
| +name as seen from Fortran. If no binding name is specified, as for TP,
|
| +the C binding name is the (lowercase) Fortran binding name. If a
|
| +binding name is specified, only a single variable may be after the
|
| +double colon. Note of warning: You cannot use a global variable to
|
| +access ERRNO of the C library as the C standard allows it to be a
|
| +macro. Use the `IERRNO' intrinsic (GNU extension) instead.

|
| +
|
| +7.1.4 Interoperable Subroutines and Functions
|
| +---------------------------------------------
|
| +
|
| +Subroutines and functions have to have the `BIND(C)' attribute to be
|
| +compatible with C. The dummy argument declaration is relatively
|
| +straightforward. However, one needs to be careful because C uses
|
| +call-by-value by default while Fortran behaves usually similar to
|
| +call-by-reference. Furthermore, strings and pointers are handled
|
| +differently. Note that only explicit size and assumed-size arrays are
|
| +supported but not assumed-shape or allocatable arrays.
|
| +
|
| + To pass a variable by value, use the `VALUE' attribute. Thus the
|
| +following C prototype
|
| +
|
| + `int func(int i, int *j)'
|
| +
|
| + matches the Fortran declaration
|
| +
|
| + integer(c_int) function func(i,j)
|
| + use iso_c_binding, only: c_int
|
| + integer(c_int), VALUE :: i
|
| + integer(c_int) :: j
|
| +
|
| + Note that pointer arguments also frequently need the `VALUE'
|
| +attribute.
|
| +
|
| + Strings are handled quite differently in C and Fortran. In C a string
|
| +is a `NUL'-terminated array of characters while in Fortran each string
|
| +has a length associated with it and is thus not terminated (by e.g.
|
| +`NUL'). For example, if one wants to use the following C function,
|
| +
|
| + #include <stdio.h>
|
| + void print_C(char *string) /* equivalent: char string[] */
|
| + {
|
| + printf("%s\n", string);
|
| + }
|
| +
|
| + to print "Hello World" from Fortran, one can call it using
|
| +
|
| + use iso_c_binding, only: C_CHAR, C_NULL_CHAR
|
| + interface
|
| + subroutine print_c(string) bind(C, name="print_C")
|
| + use iso_c_binding, only: c_char
|
| + character(kind=c_char) :: string(*)
|
| + end subroutine print_c
|
| + end interface
|
| + call print_c(C_CHAR_"Hello World"//C_NULL_CHAR)
|
| +
|
| + As the example shows, one needs to ensure that the string is `NUL'
|
| +terminated. Additionally, the dummy argument STRING of `print_C' is a
|
| +length-one assumed-size array; using `character(len=*)' is not allowed.
|
| +The example above uses `c_char_"Hello World"' to ensure the string
|
| +literal has the right type; typically the default character kind and
|
| +`c_char' are the same and thus `"Hello World"' is equivalent. However,
|
| +the standard does not guarantee this.
|
| +
|
| + The use of pointers is now illustrated using the C library function
|
| +`strncpy', whose prototype is
|
| +
|
| + char *strncpy(char *restrict s1, const char *restrict s2, size_t n);
|
| +
|
| + The function `strncpy' copies at most N characters from string S2 to
|
| +S1 and returns S1. In the following example, we ignore the return value:
|
| +
|
| + use iso_c_binding
|
| + implicit none
|
| + character(len=30) :: str,str2
|
| + interface
|
| + ! Ignore the return value of strncpy -> subroutine
|
| + ! "restrict" is always assumed if we do not pass a pointer
|
| + subroutine strncpy(dest, src, n) bind(C)
|
| + import
|
| + character(kind=c_char), intent(out) :: dest(*)
|
| + character(kind=c_char), intent(in) :: src(*)
|
| + integer(c_size_t), value, intent(in) :: n
|
| + end subroutine strncpy
|
| + end interface
|
| + str = repeat('X',30) ! Initialize whole string with 'X'
|
| + call strncpy(str, c_char_"Hello World"//C_NULL_CHAR, &
|
| + len(c_char_"Hello World",kind=c_size_t))
|
| + print '(a)', str ! prints: "Hello WorldXXXXXXXXXXXXXXXXXXX"
|
| + end
|
| +
|
| + C pointers are represented in Fortran via the special derived type
|
| +`type(c_ptr)', with private components. Thus one needs to use intrinsic
|
| +conversion procedures to convert from or to C pointers. For example,
|
| +
|
| + use iso_c_binding
|
| + type(c_ptr) :: cptr1, cptr2
|
| + integer, target :: array(7), scalar
|
| + integer, pointer :: pa(:), ps
|
| + cptr1 = c_loc(array(1)) ! The programmer needs to ensure that the
|
| + ! array is contiguous if required by the C
|
| + ! procedure
|
| + cptr2 = c_loc(scalar)
|
| + call c_f_pointer(cptr2, ps)
|
| + call c_f_pointer(cptr2, pa, shape=[7])
|
| +
|
| + When converting C to Fortran arrays, the one-dimensional `SHAPE'
|
| +argument has to be passed. Note: A pointer argument `void *' matches
|
| +`TYPE(C_PTR), VALUE' while `TYPE(C_PTR)' matches `void **'.
|
| +
|
| + Procedure pointers are handled analogously to pointers; the C type is
|
| +`TYPE(C_FUNPTR)' and the intrinsic conversion procedures are
|
| +`C_F_PROC_POINTER' and `C_FUNLOC'.
|
| +
|
| + The intrinsic procedures are described in *note Intrinsic
|
| +Procedures::.

|
| +Language Interoperability Tools,
|
| +`http://chasm-interop.sourceforge.net/', which provide an interface to
|
| +GNU Fortran's array descriptor.
|
| +
|
| + The technical report 29113 will presumably also include support for
|
| +C-interoperable `OPTIONAL' and for assumed-rank and assumed-type dummy
|
| +arguments. However, the TR has neither been approved nor implemented in

|
| +7.2 GNU Fortran Compiler Directives
|
| +===================================
|
| +
|
| +The Fortran standard standard describes how a conforming program shall
|
| +behave; however, the exact implementation is not standardized. In order
|
| +to allow the user to choose specific implementation details, compiler
|
| +directives can be used to set attributes of variables and procedures
|
| +which are not part of the standard. Whether a given attribute is
|
| +supported and its exact effects depend on both the operating system and
|
| +on the processor; see *note C Extensions: (gcc)Top. for details.
|
| +
|
| + For procedures and procedure pointers, the following attributes can
|
| +be used to change the calling convention:
|
| +
|
| + * `CDECL' - standard C calling convention
|
| +
|
| + * `STDCALL' - convention where the called procedure pops the stack
|
| +
|
| + * `FASTCALL' - part of the arguments are passed via registers
|
| + instead using the stack
|
| +
|
| + Besides changing the calling convention, the attributes also
|
| +influence the decoration of the symbol name, e.g., by a leading
|
| +underscore or by a trailing at-sign followed by the number of bytes on
|
| +the stack. When assigning a procedure to a procedure pointer, both
|
| +should use the same calling convention.
|
| +
|
| + On some systems, procedures and global variables (module variables
|
| +and `COMMON' blocks) need special handling to be accessible when they
|
| +are in a shared library. The following attributes are available:
|
| +
|
| + * `DLLEXPORT' - provide a global pointer to a pointer in the DLL
|
| +
|
| + * `DLLIMPORT' - reference the function or variable using a global
|
| + pointer
|
| +
|
| + The attributes are specified using the syntax
|
| +
|
| + `!GCC$ ATTRIBUTES' ATTRIBUTE-LIST `::' VARIABLE-LIST
|
| +
|
| + where in free-form source code only whitespace is allowed before
|
| +`!GCC$' and in fixed-form source code `!GCC$', `cGCC$' or `*GCC$' shall
|
| +start in the first column.
|
| +
|
| + For procedures, the compiler directives shall be placed into the body
|
| +of the procedure; for variables and procedure pointers, they shall be in
|
| +the same declaration part as the variable or procedure pointer.

|
| +
|
| + Even if you are doing mixed-language programming, it is very likely
|
| +that you do not need to know or use the information in this section.
|
| +Since it is about the internal structure of GNU Fortran, it may also
|
| +change in GCC minor releases.
|
| +
|
| + When you compile a `PROGRAM' with GNU Fortran, a function with the
|
| +name `main' (in the symbol table of the object file) is generated,
|
| +which initializes the libgfortran library and then calls the actual
|
| +program which uses the name `MAIN__', for historic reasons. If you link
|
| +GNU Fortran compiled procedures to, e.g., a C or C++ program or to a
|
| +Fortran program compiled by a different compiler, the libgfortran
|
| +library is not initialized and thus a few intrinsic procedures do not
|
| +work properly, e.g. those for obtaining the command-line arguments.
|
| +
|
| + Therefore, if your `PROGRAM' is not compiled with GNU Fortran and
|
| +the GNU Fortran compiled procedures require intrinsics relying on the
|
| +library initialization, you need to initialize the library yourself.
|
| +Using the default options, gfortran calls `_gfortran_set_args' and
|
| +`_gfortran_set_options'. The initialization of the former is needed if
|
| +the called procedures access the command line (and for backtracing);
|
| +the latter sets some flags based on the standard chosen or to enable
|
| +backtracing. In typical programs, it is not necessary to call any
|
| +initialization function.
|
| +
|
| + If your `PROGRAM' is compiled with GNU Fortran, you shall not call
|
| +any of the following functions. The libgfortran initialization
|
| +functions are shown in C syntax but using C bindings they are also
|
| +accessible from Fortran.

|
| + `_gfortran_set_options' sets several flags related to the Fortran
|
| + standard to be used, whether backtracing or core dumps should be
|
| + enabled and whether range checks should be performed. The syntax
|
| + allows for upward compatibility since the number of passed flags
|
