Function Delay Dev C++

Definition

Sep 01, 2009  So either include the necessary header file, or, if the function exists in an external library as you mentioned, use extern at the top of the file: extern void sleep(int); //or whatever the signature is. May 21, 2016  this program dont work on dev c, how can i use delay function on dev? #include #include #include using namespace std. Jan 22, 2013  Neon-Vibe wrote I was wondering if anybody new a command that can be used in c to add a time delay between when commands are carried out. Preferably the duration of the delay can be set by the programmer. The above example will use up CPU processes while waiting. The most efficient method is to use the Sleep or SleepEx functions from the Windows.h Header Library. Jul 18, 2017  In this post, we will see how to give a time delay in C code. Basic idea is to get current clock and add the required delay to that clock, till current clock is less then required clock run an empty loop. Here is implementation with a delay function.

Creates a task that will complete after a time delay.

Overloads

Delay(TimeSpan, CancellationToken)

Creates a cancellable task that completes after a specified time interval.

Delay(Int32, CancellationToken)

Creates a cancellable task that completes after a specified number of milliseconds.

Delay(Int32)

Creates a task that completes after a specified number of milliseconds.

Delay(TimeSpan)

Creates a task that completes after a specified time interval.

Creates a cancellable task that completes after a specified time interval.

Parameters

delay
TimeSpan

The time span to wait before completing the returned task, or TimeSpan.FromMilliseconds(-1) to wait indefinitely.

cancellationToken
CancellationToken

A cancellation token to observe while waiting for the task to complete.

Returns

Delay Function Dev C++

A task that represents the time delay.

Exceptions

delay represents a negative time interval other than TimeSpan.FromMilliseconds(-1).

-or-

The delay argument's TotalMilliseconds property is greater than MaxValue.

The task has been canceled.

The provided cancellationToken has already been disposed.

Examples

The following example launches a task that includes a call to the Delay(TimeSpan, CancellationToken) method with a 1.5 second delay. Before the delay interval elapses, the token is cancelled. The output from the example shows that, as a result, a TaskCanceledException is thrown, and the tasks' Status property is set to Canceled.

Note that this example includes a potential race condition: it depends on the task asynchronously executing the delay when the token is cancelled. Although the 1.5 second delay from the call to the Delay(TimeSpan, CancellationToken) method makes that assumption likely, it is nevertheless possible that the call to the Delay(TimeSpan, CancellationToken) method could return before the token is cancelled. In that case, the example produces the following output:

Remarks

If the cancellation token is signaled before the specified time delay, a TaskCanceledException exception results, and the task is completed in the Canceled state. Otherwise, the task is completed in the RanToCompletion state once the specified time delay has elapsed.

For usage scenarios and additional examples, see the documentation for the Delay(Int32) overload.

This method depends on the system clock. This means that the time delay will approximately equal the resolution of the system clock if the delay argument is less than the resolution of the system clock, which is approximately 15 milliseconds on Windows systems.

Creates a cancellable task that completes after a specified number of milliseconds.

Parameters

millisecondsDelay
Int32

The number of milliseconds to wait before completing the returned task, or -1 to wait indefinitely.

cancellationToken
CancellationToken

A cancellation token to observe while waiting for the task to complete.

Returns

A task that represents the time delay.

Exceptions

The millisecondsDelay argument is less than -1.

The task has been canceled.

The provided cancellationToken has already been disposed.

Examples

The following example launches a task that includes a call to the Delay(Int32, CancellationToken) method with a one second delay. Before the delay interval elapses, the token is cancelled. The output from the example shows that, as a result, a TaskCanceledException is thrown, and the tasks' Status property is set to Canceled.

Remarks

If the cancellation token is signaled before the specified time delay, a TaskCanceledException exception results, and the task is completed in the Canceled state. Otherwise, the task is completed in the RanToCompletion state once the specified time delay has elapsed.

For usage scenarios and additional examples, see the documentation for the Delay(Int32) overload.

This method depends on the system clock. This means that the time delay will approximately equal the resolution of the system clock if the millisecondsDelayLoad ipa using 3utools. argument is less than the resolution of the system clock, which is approximately 15 milliseconds on Windows systems.

Creates a task that completes after a specified number of milliseconds.

Parameters

millisecondsDelay
Int32

The number of milliseconds to wait before completing the returned task, or -1 to wait indefinitely.

Returns

A task that represents the time delay.

Exceptions

The millisecondsDelay argument is less than -1.

Examples

The following example shows a simple use of the Delay method.

Remarks

The Delay method is typically used to delay the operation of all or part of a task for a specified time interval. Most commonly, the time delay is introduced:

  • At the beginning of the task, as the following example shows.

  • Sometime while the task is executing. In this case, the call to the Delay method executes as a child task within a task, as the following example shows. Note that since the task that calls the Delay method executes asynchronously, the parent task must wait for it to complete by using the await keyword.

After the specified time delay, the task is completed in the RanToCompletion state.

This method depends on the system clock. This means that the time delay will approximately equal the resolution of the system clock if the millisecondsDelay argument is less than the resolution of the system clock, which is approximately 15 milliseconds on Windows systems.

Creates a task that completes after a specified time interval.

Parameters

delay
TimeSpan

The time span to wait before completing the returned task, or TimeSpan.FromMilliseconds(-1) to wait indefinitely.

Returns

A task that represents the time delay.

Exceptions

delay represents a negative time interval other than TimeSpan.FromMilliseconds(-1).

-or-

The delay argument's TotalMilliseconds property is greater than MaxValue.

Examples

The following example shows a simple use of the Delay method.

Remarks

After the specified time delay, the task is completed in RanToCompletion state.
