1.30.4                                            Jun 08, 2025                        MONGOC_COLLECTION_STATS(3)

       Run the collStats command to retrieve statistics about the collection.

       The command uses the mongoc_read_prefs_t set on collection.

       Errors are propagated via the error parameter.

       • collection: A mongoc_collection_t.

       • options: An optional bson_t containing extra options to pass to the collStats command.

       • reply: A maybe-NULL pointer to overwritablestorage for a bson_t to contain the results.

       • error: An optional location for a bson_error_t or NULL.

       Returns true if successful. Returns false and sets error if there are invalid arguments or  a  server  or
       network error.

       reply is always initialized and must be freed with bson_destroy().

          bool
          mongoc_collection_stats (mongoc_collection_t *collection,
                                   const bson_t *options,
                                   bson_t *reply,
                                   bson_error_t *error);

          Deprecated   since   version   1.10.0:   Use   the   $collStatsaggregationpipelinestage  with
          mongoc_collection_aggregate() instead.
