NAME

       mongoc_cursor_more - mongoc_cursor_more()

SYNOPSIS

          bool
          mongoc_cursor_more (mongoc_cursor_t *cursor);

PARAMETERS

       ยท cursor: A mongoc_cursor_t.

DESCRIPTION

       This function shall indicate if there is potentially more data to be read from the cursor.
       This is only useful with tailable cursors. Use mongoc_cursor_next for regular cursors.

       Details: mongoc_cursor_more is unreliable because it does not contact the server to see if
       there  are actually more documents in the result set. It simply returns true if the cursor
       has not begun, or if it has begun and there are  buffered  documents  in  the  client-side
       cursor,  or  if  it  has begun and the server has not yet told the cursor it is completely
       iterated.

       This is unreliable with regular queries because it returns true for a  new  cursor  before
       iteration,  even  if the cursor will match no documents. It is also true if the collection
       has been dropped on the server since the previous fetch, or if the cursor has finished its
       final batch and the next batch will be empty.

RETURNS

       true  if the cursor has locally-buffered documents, or if a round-trip to the server might
       fetch additional documents.
