REENTRANT means the program can be called from several callers simultaneously. The program obtains storage (memory) at each invocation.

Sleep (logically swapped out task) is established through STIMER macro (SVC 47)

Input and output is dependent on hardware. The time units are machine cycles, which depends both on the oscillator frequency and the oscillator periods to machine cycle conversion factor. This code puts the processor into 'idle' mode, where code execution is stopped and resumed via an interrupt.

set /p Seconds=Enter the number of seconds to sleep:

echo Sleeping ...

ping -n %Seconds% localhost >nul 2>&1

A similar trick can be used to wait a certain number of milliseconds. The <code>ping</code> utility includes a <code>/w</code> option which specifies the timeout to wait for a reply. This coupled with an unreachable address (where the full timeout will be needed) leads to the following:

 

{{works with|Windows 2000}}

set /p MilliSeconds=Enter the number of milliseconds to sleep:

echo Sleeping ...

ping -n 1 -w %MilliSeconds% 1.2.3.4 >nul 2>&1

 

Starting with Windows Vista there is a command-line utility to wait a number of seconds:

=={{header|Erlang}}==

 

Erlang doesn't really have such a thing as a main thread. However, sleeping any process can be done with the <tt>timer:sleep/1</tt> function:

io:format("Sleeping...~n"),

timer:sleep(1000), %% in milliseconds

 

It is to be noted that Erlang's sleep function is implemented in Erlang with a timeout on a <tt>receive</tt>, so you may sometimes encounter the following way of sleeping a process:

io:format("Sleeping...~n"),

receive

after 1000 -> ok %% in milliseconds

end,

 

which is the way it is implemented in the <tt>timer</tt> module.

Sample input/output

=={{header|Frink}}==

In Frink, all values have units of measure, and sleep functions take units of time, which can be seconds, nanoseconds, minutes, hours, etc. The user may enter values like "3 hours" or "1 ms". The units of measure are captured as first-class values in the language, and not hidden in comments nor implied in APIs.

=={{header|Go}}==

Technically, this varies from the task by sleeping the main ''goroutine'' rather than the main ''thread''. The Go runtime multiplexes goroutines to operating system threads and the language does not provide direct access to threads.

=={{header|Lhogho}}==

The Logo version works without modification. Another way to Sleep, in the Windows version of Lhogho, is to use the Win32 function, viz

make "Long "U4

Sleep :n ; units: 1/1000th of a second

print [Awake.]

=={{header|Lua}}==

{{libheader|LuaSocket}}

The input does not need to be a whole number, eg. "0.5" would cause the program to wait for half a second.

io.write("Input a number of seconds to sleep: ")

local input = io.read("*number")

print("Sleeping")

socket.sleep(input)

A similar effect could be achieved using a "busy" loop but the function in lua-socket is gentler on your CPU.

Note that sleep() is entirely inappropriate for GUI applications, which should instead set a routine to resume processing

(that would be timer_cb below), activate a timer (set RUN to true), and relinquish control to the event loop. Another

excellent way to perform extended processing without making an application unresponsive is via an IDLE_ACTION, provided

that also regularly relinquishes control to the event loop, and can pick up where it left off when next invoked.

Coding note: &nbsp; the &nbsp; '''!''' &nbsp; subroutines (above) deal mostly with determining what version of REXX is being invoked and what operating system is being used; &nbsp; and based on that information, appropriate flags (variables) are set. &nbsp; This is an example of a robust boilerplate code checking for various versions of REXX and operating systems, and it also defines additional flags not used within this particular program.

=={{header|Scheme}}==

The following works in Chicken Scheme:

 

(use format)

(use srfi-18)

(format #t "Awake!~&"))

(format #t "You must enter a number~&")))

 

Scheme implementations also provide alternative approaches. For example, Chicken Scheme has a 'posix' library which includes a 'sleep' function.

The [http://seed7.sourceforge.net/libraries/duration.htm duration.s7i] library defines the function ''wait'', which takes an argument of type ''duration''. Functions to create durations with years, months, days, hours, minutes, seconds and micro seconds exist also.

 

include "duration.s7i";

 

wait(secondsToSleep . SECONDS);

This uses the [http://www.openbsd.org/cgi-bin/man.cgi?query=sleep&apropos=0&sektion=1&manpath=OpenBSD+Current&arch=i386&format=html sleep(1)] command. POSIX sleep(1) only takes an integer, as in <tt>sleep 2</tt>, so you can only sleep for a whole number of seconds. Some systems extend sleep(1) to take a decimal fraction, as in <tt>sleep 2.5</tt>.

=={{header|X86 Assembly}}==

This sleep subroutine takes the number of seconds to sleep as a parameter.

The actual linux syscall that I use to implement this takes a time struct (seconds at the first qword and nanoseconds at the second) as the first argument. Optionally you can pass another time stuct as a second argument. In the event that the sleep is interrupted by a system event, linux will fill this second struct with the remaining time so the syscall can be called again with the remaining sleep time.
