NAME

       mongoc_client_command_simple - mongoc_client_command_simple()

SYNOPSIS

          bool
          mongoc_client_command_simple (mongoc_client_t *client,
                                        const char *db_name,
                                        const bson_t *command,
                                        const mongoc_read_prefs_t *read_prefs,
                                        bson_t *reply,
                                        bson_error_t *error);

       This  is  a simplified interface to mongoc_client_command(). It returns the first document
       from the result cursor into reply. The client's read preference, read concern,  and  write
       concern are not applied to the command.

       WARNING:
          reply is always set, and should be released with bson_destroy().

       This function is not considered a retryable read operation.

PARAMETERS

       • client: A mongoc_client_t.

       • db_name: The name of the database to run the command on.

       • command: A bson_t containing the command specification.

       • read_prefs:   An   optional   mongoc_read_prefs_t.  Otherwise,  the  command  uses  mode
         MONGOC_READ_PRIMARY.

       • reply: A location for the resulting document.

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

ERRORS

       Errors are propagated via the error parameter.

RETURNS

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

       This  function  does  not  check  the  server  response for a write concern error or write
       concern timeout.
