Detailed Description

Timer allowing to measure time between a start point and a stop point.

This timer allows the user to measure user time, system time and wallclock time between two points. Basically, user time is time spent in developer code ; system time is time spent during the IO wait and system calls ; wallclock is the difference of time we could observe by measuring time with a watch.

Member Function Documentation

long int eoTimer::usertime

(

)

[inline]

Measures the user time spent since the last restart().

If the number of elapsed seconds is zero, the spent milliseconds are added to a remainder. If the remainder exceeds one second, it is added to the number of elapsed seconds.

Returns:

Number of seconds elapsed in user space.

long int eoTimer::systime

(

)

[inline]

Measures the system time spent since the last restart().

If the number of elapsed seconds is zero, the spent milliseconds are added to a remainder. If the remainder exceeds one second, it is added to the number of elapsed seconds.

Returns:

Number of seconds elapsed in system (kernel) space.
