Probably the simplest solution would be to treat it as fixed size and
use the maximum possible size for the object.
From http://linux.die.net/man/7/inotify
Specifying a buffer of size
sizeof(struct inotify_event) + NAME_MAX + 1
will be sufficient to read at least one event.

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
