[julia-users] Julia type for a recursive C struct with anonymous unions

[sudomeme]

I am new to Julia with mostly C and some MATLAB background.  Julia seems to 
provide an easy way to write C like code with MATLAB ease!  To get started, 
I am trying understand C interface. Is it be possible to create a Julia 
type for the following struct?

typedef struct itree {
  bool isLeaf; 
  int n; //number of elements
  union {
int *i; //(isLeaf == 1): pointer to int array
struct itree **s; //(isLeaf == 0): pointer to itree array
  };
} itree;

It seems, that the size of the pointer should be the same. So, anonymous 
union should be possible.  
I would appreciate any suggestions.

Thanks,
