[Numpy-discussion] f2py and C functions/subroutines/structs

[lorenzo bolla]

I tried to write my own prova2.pyf and this is it:

----------------------------------------------------------------

!    -*- f90 -*-
! Note: the context of this file is case sensitive.

python module prova

interface

   function incr(x)
     real, dimension(2), intent(c) :: incr
     real, dimension(2), intent(c,in) :: x
   end function incr

   function incr0(x)
     integer intent(c) :: incr0
     integer intent(c,in) :: x
   end function incr0

   subroutine incr1(x)
     intent(c) :: incr1
     integer intent(c,in,out) :: x
   end subroutine incr1

end interface

end python module prova

! This file was auto-generated with f2py (version:2_3473).
! See http://cens.ioc.ee/projects/f2py2e/

----------------------------------------------------------------


Unfortunately, only the function incr0 works.
incr1 gives a segmentation fault and incr does not return an array (or
better a struct) as I would...
any hints?

thank you!
L.
