[Chicken-users] how to declare foreign variably size structs?

[Geoffrey]

Hi I am trying to declare of variably sized c struct as a foreign declaration.

The one i am after is:

struct inotify_event
{
  int wd;                /* Watch descriptor.  */
  uint32_t mask;        /* Watch mask.  */
  uint32_t cookie;        /* Cookie to synchronize two events.  */
  uint32_t len;                /* Length (including NULs) of name.  */
  char name __flexarr;        /* Name.  */
};

Note that name field is variably sized. I believe in C you would allocate a larger block of memory and then cast it to  (inotify_event*). 

By the skills of copy and paste i can do fixed size,and i can do a blob. But not a variable struct.

Some help would be appreciated.

Thanks
