What we've done is create two Task-derived objects that test different locking mechanisms. The Token object uses ACE_Token and the Mutex object uses ACE_Mutex. When you execute the application you should see quite a difference in thread utilization. At the end of the tutorial I've included a link to the output of a typical run of the application.

// Get our two Test derivatives...
#include "Token_i.h"
#include "Mutex_i.h"
int main(int,char**)
{
// See what an ACE_Token does for us.
Token token;
token.run();
// And now the ACE_Mutex.
Mutex mutex;
mutex.run();
return(0);
}
