This function is superseded by mongoc_database_command_with_opts(), mongoc_database_read_command_with_opts(), mongoc_database_write_command_with_opts(), and mongoc_database_read_write_command_with_opts().


This function creates a cursor which will execute the command when mongoc_cursor_next() is called on it. The database’s read preference, read concern, and write concern are not applied to the command, and mongoc_cursor_next() will not check the server response for a write concern error or write concern timeout.


  • database: A mongoc_database_t.
  • flags: A mongoc_query_flags_t.
  • skip: The number of documents to skip on the server.
  • limit: The maximum number of documents to return from the cursor.
  • batch_size: Attempt to batch results from the server in groups of batch_size documents.
  • command: A bson_t containing the command.
  • fields: An optional bson_t containing the fields to return. NULL for all fields.
  • read_prefs: An optional mongoc_read_prefs_t. Otherwise, the command uses mode MONGOC_READ_PRIMARY.


A mongoc_cursor_t.

The cursor should be freed with mongoc_cursor_destroy().
