I'm trying to interface with libnauty to do some graph-isomorphism stuff. I've
gone through the docs many times but haven't been able to find a way to
adequately write a certain struct type.
In nauty.h:820 there's an incomplete definition followed by a struct that
contains a pointer to it, then the completed definition pointing back to the
other struct:
struct optionstruct;
typedef struct
{
...
void (*init)(..., struct optionstruct*, ...);
...
} dispatchvec;
typedef struct optionstruct
{
...
dispatchvec *dispatch;
...
} optionblk;
If I try to write these two struct types with define-cstruct, then the
dispatchvec's usage of _optionstruct-pointer is an undefined identifier error.
I currently replaced this with _pointer to get it all to compile. That might
work. I'm just wondering if I missed something. Mutual recursion seems like an
important feature.
