This involves modifying the appropriate kernel function to handle the sleep system call and adding any necessary data structures or helper functions. Implement the sleep system call: The final step is to implement the sleep system call in the kernel code.This mechanism should be updated to handle the sleep system call number. Modify the system call dispatcher: The system call dispatcher is responsible for determining which system call to execute based on the system call number passed by the user program.This number should be added to the system call header file and the system call dispatching mechanism. Assign a system call number: Next, assign a unique number to the sleep system call.This information should be added to the system call header file. Define the system call interface: The first step is to define the interface for the sleep system call, including its name, arguments, and return value.Here are the general steps to implement the sleep system call in an operating system: The implementation of the sleep system call in an operating system involves modifying several components of the kernel, including the system call interface, system call dispatching mechanism, and the kernel code that implements the sleep system call. The sleep system call is used to pause the execution of a program for a specified amount of time. Interrupted Exception will be thrown when any other thread interrupts when the thread is sleeping.Whenever you use this method, it will pause the current thread execution.

Points to remember while using the Tread.sleep() : You sleep a thread for thespecified time,the thread scheduler picks up another thread and Note - In the above example you can notice that at a time only one thread has been executed and if ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.
