I did use Inline::Struct, is it the same ?
I was not able to make it work with a
routine returning a pointer on a struct, in addition, it seems that
I cannot have a:
double *a
inside the structure.

Inline::Struct seems OK to declare and allocate a new Structure with
a new, like:
my $profile = Inline::Struct::array_sized -> new ;

but in my case, the memory space is allocated in the
subroutine and only the pointer on the structure is returned. I did not
find a way to access to the elements of the structure.

$$profile -> element     does no work (is element is an element of the 
c structure)
