ipcSleepMilli

ipcSleepMilli( 
x_time 
) 
=> t

Description

Causes the parent process to be delayed for the given number of milliseconds. Use the otherwise identical ipcSleep function to specify the delay in seconds.

Arguments

x_time

Number of milliseconds for the parent to sleep.

Value Returned

t	Always returns t.

Examples

The following example illustrates the performance characteristics for more, shorter delays as compared to fewer, longer delays.

> procedure(SleepPerformance(x_numIters x_milliPerIter)
    let( (measured)
     measured = measureTime(
   for(i 1 x_numIters ipcSleepMilli(x_milliPerIter)) )
  printf("for %d iterations of %dms, (userTime sysTime wallclock)
    is (%f %f %f)\n"
   x_numIters x_milliPerIter
   nth(0 measured) nth(1 measured) nth(2 measured) )
  ))

> (SleepPerformance 2000 50)
for 2000 iterations of 50ms, (userTime sysTime wallclock) is (0.018998 0.016997 100.167697)
t

> (SleepPerformance 50 2000)
for 50 iterations of 2000ms, (userTime sysTime wallclock) is (0.000999 0.001000 100.083947)
t
