For arguments of @code{CHARACTER} type, the character length is passed
-as a hidden argument at the end of the argument list. For
-deferred-length strings, the value is passed by reference, otherwise
-by value. The character length has the C type @code{size_t} (or
-@code{INTEGER(kind=C_SIZE_T)} in Fortran). Note that this is
-different to older versions of the GNU Fortran compiler, where the
-type of the hidden character length argument was a C @code{int}. In
-order to retain compatibility with older versions, one can e.g. for
-the following Fortran procedure
-
-@smallexample
-subroutine fstrlen (s, a)
- character(len=*) :: s
- integer :: a
- print*, len(s)
-end subroutine fstrlen
-@end smallexample
-
-define the corresponding C prototype as follows:
-
-@smallexample
-#if __GNUC__ > 6
-typedef size_t fortran_charlen_t;
-#else
-typedef int fortran_charlen_t;
-#endif
-
-void fstrlen_ (char*, int*, fortran_charlen_t);
-@end smallexample
-
-In order to avoid such compiler-specific details, for new code it is
-instead recommended to use the ISO_C_BINDING feature.
-
-Note with C binding, @code{CHARACTER(len=1)} result variables are
-returned according to the platform ABI and no hidden length argument
-is used for dummy arguments; with @code{VALUE}, those variables are
-passed by value.
