  • Agenda and Pre-requisites2:39
  • Join Telegram Group0:13
  • Timer Relevance2:08

    Explore the relevance of timers across networking and security contexts, and learn to implement Linux and POSIX timer APIs to build custom, controllable timers.

  • Timer Types2:57
  • Posix APIs for Timers2:10
  • Timer Design7:00
  • Timer Creation Steps - Theory9:44
  • Timer Implementation and Demo14:15

    Learn to implement and demonstrate Linux timers in C, including creating timers, configuring callback functions, starting countdowns, and converting one-shot timers to periodic with an interval.

Requirements

  • C coding language, Linux Operating System only
  • You should familiar with basic data structures such as linked list and function pointers.
  • Basics of Multi-threading - to start a thread
  • Must know Callbacks (function pointers)

Description

O Ghosh !! I just cannot shout-out more how important TIMERS are in almost all applications or projects. Timers are used to schedule events to be triggered or fired in future. How have you been doing this till now ?

Timers Use case Scenarios :

1. Firing One time future Event : Delete something after 100 seconds

2. Firing Repeated Regular future Events : Send packet to machine X after every 5 seconds

3. Periodic Waits : Try something 5 times at an interval of 3 seconds


How would you design a timer ?   PET Question for interview. So better prepare for it.


About this Course This is short project based course, yet important course to cover Data Structures and Algorithms involved in designing efficient timers.  We shall be using C as a programming language, but you are free to use your favorite programming language. This course is Programming language agnostic.


Course Pre-requisite

If you can code in any programming language, that suffice.

You should familiar with basic data structures such as linked list and function pointers.

Basics of Multi-threading


Also, Please just do not sit and watch my codes. Write your own codes, even if it is same as mine !


No Third Party libraries

Whatever logic you implement, you need to implement it from scratch. This course do not suggest taking help of any third party library to get the jobs done. Use of external libraries completely defeats the purpose of the course. However, it is recommended to use third party libraries for commonly used data structures such as linked lists/Trees/Queues etc which saves a lot of time implementing these data structures.
