Dos.h delay function in C: Here, we will learn about the delay function of dos.h header file in C through a simple example/program. Delay function is used to hold the program's execution for given. Delay in C: delay function is used to suspend execution of a program for a particular time. Declaration: void delay(unsigned int); Here unsigned int is the number of milliseconds (remember 1.

Jan 10, 2017 The delay function is used to suspend execution of a program for a particular time. Declaration: void delay(unsigned int); Here unsigned int is the number of milliseconds (remember 1 second = 1000 milliseconds). To use delay function in your. The delay function is built upon a C library function called clock. The clock function returns a time value in clock ticks, which is based on the processor’s speed. The value returned is of the clockt variable type. You can use subsequent reads of the clock function to determine elapsed time. Delay in C: delay function is used to suspend execution of a program for a particular time. Declaration: void delay (unsigned int); Here unsigned int is the number of milliseconds (remember 1 second = 1000 milliseconds). To use delay function in your program you should include the 'dos.h' header file which is not a part of standard C library.

Introduction

This article is about delayed execution for a function that we can have in setInterval.

We all know, if we want to execute a function or run a task after certain interval of time then we can schedule a call. This can be done in two ways:

setTimeout which allows us to run a function once after the interval of time.
setInterval which allows us to run a function repeatedly, starting after the interval of time, then repeating continuously at that interval.

Here, we will look into how we can delay a function execution in setInterval() and see how it behaves.

setInterval

The setInterval method has the same syntax as setTimeout:

All arguments have the same meaning. But unlike setTimeout it runs the function not only once, but regularly after the given interval of time.

Let us consider this snippet:

Observe the output:

It prints the message after 2 seconds continuously.

It is possible that execution of test function turns out to be longer than we expected and takes more than 2000ms.

what will happen in such case?

I am adding a setTimeout() with a delay of 5000ms which exceeds the interval specified in setInterval().

If you notice the output in your browser console, you would notice the output

after a delay of 7000ms.

And then you could see the following in an interval of 2000ms
received value is : 2
received value is : 3
received value is : 4

In this case the engine waits for test function to complete, then checks the scheduler and if the time is up, runs it again immediately.

In the edge case, if the function always executes longer than delay ms, then the calls will happen without a pause at all.

Such a case might appear while making an API call inside the function/callback mentioned in setTimeinterval().

Yeah that's about delay in setInterval. Hope this was helpful.
