    for ( long i = 0 ; i < 10000000 ; ++i )
     {
        .. put some CPU-intensive computations here
     }

  } // end of the scope, destroy chrono

Parameters:

svc	pointer to Chrono Service
tag	the unique tag

Definition at line 53 of file Chrono.h.

    : m_chrono ( 0 )
  { if ( 0 != svc ) { m_chrono = svc -> chronoStart ( tag ) ; } }
