Python | os.sched_rr_get_interval() method

OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality.

OS module contains some methods which provides an interface to the scheduler and used to control how a process is allocated CPU time by the operating system.
os.sched_rr_get_interval() method in Python is used to get the Round Robin quantum in seconds for the process indicated by the specified process id.

What is Round Robin quantum?
In the Round-Robin scheduling policy, processes are dispatched in a FIFO manner but are given a limited amount of CPU time called a time-slice or a quantum.

Note: This method is only available on some UNIX platforms.

Syntax: os.sched_rr_get_interval(pid)

pid: The process id of the process whose Round Robin quantum value is required. A pid of 0 represents the calling process.

Return Type: This method returns an float value which represents the Round Robin quantum in seconds.

Code: Use of os.sched_rr_get_interval() method





# Python program to explain os.sched_rr_get_interval() method  
# importing os module 
import os
# get the Round-Robin time qunatum
# of the current process
# A pid of 0 represnts the
# the calling process 
pid = 0
quantum = os.sched_rr_get_interval(pid)
# print round robin time qunatum
print("Round Robin time quantum (in seconds):", quantum)



Round Robin time quantum (in seconds): 0.016
