Timing functions

power search

The following timing functions allow to compute the number of seconds elapsed since a given moment. They are generally used to compute the response time of a program.

1. TimerStart

Use subprocedure timerStart to start computing the elapsed time.
Example:

 *   Set timer for calculating execution time
C                   callp     TimerStart()

1. TimerElapsed

Use subprocedure timerElapsed to receive the number of seconds elapsed since the last timerStart.
Example:

 * Program timing variable
D sec             s             15p 6
C                   eval      sec = TimerElapsed()
C                   callp     updhtmlvar('runtime':%editc(sec:'N'))
C                   callp     wrtsection('runtime')
