ABA_CPUTIMER::ABA_CPUTIMER ( ABA_GLOBAL * glob )

After the application of the constructor the timer is not running, i.e., to measure time it has to be started explicitly.

Parameters:

glob

A pointer to a global object.

This constructor initializes the total time of the timer.

The timer is not running, too.

Parameters:

	glob	A pointer to a global object.
	centiSeconds	The intial value of the total time in $1\over 100$ seconds.

virtual ABA_CPUTIMER::~ABA_CPUTIMER ( ) [virtual]

The destructor.

virtual long ABA_CPUTIMER::theTime ( ) const [private, virtual]

Returns the used cpu time in $1\over100$ seconds since the start of the program.

This function redefines the pure virtual function of the base class ABA_TIMER.

: Since CLOCKS_PER_SEC can be 1000000 the standard library function clock() returns negative values after about than 35 minutes. Hence we measure the cpu time with the function times which is common on / systems, although not defined in the /-ANSI-standard.

Implements ABA_TIMER.
