NAME

Language::Befunge::IP::lib::HRTI - High-Resolution Timer extension

DESCRIPTION

The HRTI fingerprint (0x48525449) allows a Funge program to measure elapsed time much more finely than the clock values returned by y.

The timer and mark-list are considered global and static, shared amongst all IP's, in order to retain tame behaviour. This timer is not affected by 'time travel' contrivances.

FUNCTIONS

new

Create a new HRTI instance.

Precision infos

$n = G(): Granularity pushes the smallest clock tick the underlying system can reliably handle, measured in microseconds.

Time measurements

M(): Mark designates the timer as having been read by the IP with this ID at this instance in time.
$microseconds = T(): Timer pushes the number of microseconds elapsed since the last time an IP with this ID marked the timer. If there is no previous mark, acts like r.
E(): Erase mark erases the last timer mark by this IP (such that T above will act like r).
$microseconds = S(): Second pushes the number of microseconds elapsed since the last whole second.
