SYNOPSIS

          #define BSON_ITER_HOLDS_DOCUMENT(iter) \
             (bson_iter_type ((iter)) == BSON_TYPE_DOCUMENT)

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

PARAMETERS

       • iter: A bson_iter_t.

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

       • document: A location for the document buffer.

DESCRIPTION

       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.
