=========================

Synopsis
--------

.. code-block:: c

  mongoc_cursor_t *
  mongoc_database_command (mongoc_database_t *database,
                           mongoc_query_flags_t flags,
                           uint32_t skip,
                           uint32_t limit,
                           uint32_t batch_size,
                           const bson_t *command,
                           const bson_t *fields,

This function is superseded by :symbol:`mongoc_database_command_with_opts()`, :symbol:`mongoc_database_read_command_with_opts()`, :symbol:`mongoc_database_write_command_with_opts()`, and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

Description
-----------

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

Parameters
----------

* ``database``: A :symbol:`mongoc_database_t`.
* ``flags``: A :symbol:`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 :symbol:`bson:bson_t` containing the command.
* ``fields``: An optional :symbol:`bson:bson_t` containing the fields to return. ``NULL`` for all fields.
* ``read_prefs``: An optional :symbol:`mongoc_read_prefs_t`. Otherwise, the command uses mode ``MONGOC_READ_PRIMARY``.

Returns
-------

A :symbol:`mongoc_cursor_t`.

The cursor should be freed with :symbol:`mongoc_cursor_destroy()`.
