       This function is deprecated and should not be used in new code.

       Please use mongoc_cursor_new_from_command_reply_with_opts() instead.

       When    migrating    from   the   deprecated   mongoc_cursor_new_from_command_reply()   to
       mongoc_cursor_new_from_command_reply_with_opts(), note that options previously  passed  to
       the reply argument (e.g. "batchSize") must instead be provided in the opts argument.


       · client: A mongoc_client_t.

       · reply:  The  reply to a command, such as "aggregate", "find", or "listCollections", that
         returns     a     cursor     document.     The      reply      is      destroyed      by
         mongoc_cursor_new_from_command_reply and must not be accessed afterward.

       · server_id: The opaque id of the server used to execute the command.


       Some  MongoDB  commands  return  a  "cursor"  document.  For example, given an "aggregate"

          { "aggregate" : "collection", "pipeline" : [], "cursor" : {}}

       The server replies:

             "cursor" : {
                "id" : 1234,
                "ns" : "db.collection",
                "firstBatch" : [ ]
             "ok" : 1

       mongoc_cursor_new_from_command_reply  is  a  low-level   function   that   initializes   a
       mongoc_cursor_t  from  such  a reply. Additional options such as "tailable" or "awaitData"
       can be included in the reply.

       When synthesizing a completed cursor response that has no more batches (i.e.  with  cursor
       id 0), set server_id to 0 as well.

       Use  this  function  only  for  building  a  language driver that wraps the C Driver. When
       writing applications in C, higher-level functions such as mongoc_collection_aggregate  are
       more appropriate, and ensure compatibility with a range of MongoDB versions.
