Function CSTL_wstring_data

pub unsafe extern "C" fn CSTL_wstring_data(
    instance: CSTL_WideStringRef,
) -> *mut wchar_t

Returns a pointer to the underlying null-terminated array serving as character storage.

If CSTL_wstring_empty(instance) == true the pointer is still valid and points to a single null character.

The range [CSTL_wstring_data(instance), CSTL_wstring_data(instance) + size] is always valid.

The array may be mutated through the returned pointer excluding the past-the-end null terminator.
