void
bson_iter_document (const bson_iter_t *iter,
                    uint32_t *document_len,
                    const uint8_t **document);

• iter: A bson_iter_t.
• document_len: A location for the length of the document in bytes.
• document: A location for the document buffer.

The bson_iter_document() function shall retrieve the raw buffer of a sub-document from iter. iter MUST be on an element that is of type BSON_TYPE_DOCUMENT. This can be verified with bson_iter_type() or the BSON_ITER_HOLDS_DOCUMENT() macro.
