equivalent of fftw_r2r_kind in fortran 90

Hi all
In the advanced interface of fftw3 library, on pg 31 of the manual

fftw_plan fftw_plan_many_r2r(int rank, const int *n, int howmany, double
*in, const int *inembed, int istride, int idist, double *out, const int
*onembed, int ostride, int odist, const fftw_r2r_kind *kind, unsigned
flags);

I know that equivalent of fftw_plan is integer*8. On the same grounds
how to declare the "const fftw_r2r_kind *" variable in fortran 90? Is it
an integer*8 array or is it character array?

For my case the rank is 2 And I want to do FFTW_REDFT00 in both the
directions.

I read the documentation but they did not discuss anything about it.

thanks for any input
raju
