Returns a sentinel terminated array of `match_t` objects. Returns a sentinel terminated array of `match_t` objects.
The sentinel object is defined as `(match_t){ .position = -1, .width = -1, };`. The sentinel object is defined as `(match_t){ .position = -1, .width = -1, };`.
The position and width of non-sentinel `match_t`s is guaranteed to be => 0.
```C
bool is_sentinel(const match_t * const match);
```
This is the function you must check whether a `match_t` is a sentinel or not.
I.e. make this the break condition while looping the results.
