-/* fftwf77.c:
-
- FORTRAN-callable "wrappers" for some of the FFTW routines. To
- make these routines callable from FORTRAN, three things had to
- be done:
-
- * The routine names have to be in the style that is expected by
- the FORTRAN linker. This is accomplished with the F77_FUNC_
- macro. (See the file "f77_func.h".)
-
- * All parameters must be passed by reference.
-
- * Return values had to be converted into parameters (some
- Fortran implementations seem to have trouble calling C functions
- that return a value).
-
- Note that the "fftw_plan" and "fftwnd_plan" types are pointers.
- The calling FORTRAN code should use a type of the same size
- (probably "integer").
-
- The wrapper routines have the same name as the wrapped routine,
- except that "fftw" and "fftwnd" are replaced by "fftw_f77" and
- "fftwnd_f77".
