# bson_iter_array()

## Synopsis

    void
    bson_iter_array (const bson_iter_t *iter,
                     uint32_t *array_len,
                     const uint8_t **array);

## Parameters

- `iter`: A bson_iter_t.
- `array_len`: A location for the buffer length.
- `array`: A location for the immutable buffer.

## Description

The `bson_iter_array()` function shall retrieve the raw buffer of a sub-array from `iter`. `iter` MUST be on an element that is of type BSON_TYPE_ARRAY. This can be verified with bson_iter_type() or the `BSON_ITER_HOLDS_ARRAY()` macro.
