MONGOC_CLIENT_COMMAND_SIMPLE(3) libmongoc MONGOC_CLIENT_COMMAND_SIMPLE(3) 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 prefer- ence, 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 maybe-NULL pointer to overwritable storage for a bson_t to con- tain the results. * 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 in- valid arguments or a server or network error. This function does not check the server response for a write concern error or write concern timeout.
