<p>The sleep time is the sum of specified values, hours, minutes seconds and milliseconds.
|
|
A negative value can be supplied to any of them provided the total sleep time
|
|
is positive</p>
|
|
<p>Note that sleep times are always hints to be interpred by the OS how it feels
|
|
- small times may either be ignored or rounded up to a minimum timeslice. Note
|
|
also that the system clocks often have a fairly low granularity too, which complicates
|
|
measuring how long a sleep actually took.</p>
|
|
<h3>Examples</h3>
|
|
<pre> <sleep milliseconds="10"/></pre>
|
|
Sleep for about 10 mS.
|
|
<pre> <sleep seconds="2"/></pre>
|
|
Sleep for about 2 seconds.
|
|
<pre> <sleep hours="1" minutes="-59" seconds="-58"/></pre>
|
|
<p>Sleep for one hour less 59:58, or two seconds again </p>
|
|
<pre> <sleep /></pre>
|
|
Sleep for no time at all. This may yield the CPU time to another thread or process.
