The sleep keyword[edit | edit source]

sleep makes the process sleep for the number of seconds passed by the EXPRESSION seconds (integer).

It's not a good idea to mix alarm and sleep calls, as sleep is often implemented using alarm.

Syntax[edit | edit source]


Examples[edit | edit source]

The code
print "Hello " . time . "\n";
sleep 5;
print "World! " . time . "\n";
returns the two strings with a leap of about 5 s:
Hello 1424262965
World! 1424262970
