Calling mysqldump from c++

[Rudo Pribis]

Hi I'm new here.
I have a problem with calling mysqldump from c++.
My code looks like this.

void main()
{
char szCmd[]="C:\\Program Files\\MySQL\\MySQL Server 5.0\\bib\\mysqldump.exe";
_spawnl(_P_WAIT, szCmd, "mysql > C:\\Temp\\tmp.sql");
DWORD err = GetLastError();
}

I get error 87, from GetLastError .
And in command window I get text:
-- MySQL dump 10.12
--
-- Host: localhost Database: >
-- ------------------------------------------------------
-- Server version 5.0.37-community-nt

/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
/*!40103 SET @OLD_TIME_ZONE=@@TIME_ZONE */;
/*!40103 SET TIME_ZONE='+00:00' */;
/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0
*/;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;

mysqldump: Got error: 1049: Unknown database '>' when selecting the database

Does someone know, what's going on here ? I am starting be little bit screwd from this.
