Reading Directory Contents


opendir(), readdir(), and closedir():
These functions are used for directory traversal.
    opendir(): Opens a directory stream.
    readdir(): Reads the next directory entry (file or subdirectory).
    closedir(): Closes the directory stream.

Example:
#include <dirent.h> 
#include <stdio.h> 
 int main() 
{ 
 DIR *dir = opendir("."); 
 if (dir) {
 struct dirent *entry; 
 printf("Current Directory Contents\n");
 while ((entry = readdir(dir)) != NULL) 
{ 
 printf("%s\n", entry->d_name); 
 } 
 closedir(dir); } 
 return 0; 
}

FCFS and SJF

Image
CPU Scheduling in Operating Systems: In the context of operating systems, CPU scheduling involves determining which process (or task) should be executed next by the central processing unit (CPU). The goal is to maximize CPU utilization, minimize waiting time, and ensure fair allocation of resources. Various scheduling algorithms are used to achieve these objectives. First-Come-First-Serve (FCFS) Scheduling: Definition: FCFS is the simplest CPU scheduling algorithm. It is non-preemptive, meaning once a process starts executing, it cannot be interrupted until completion. Processes are placed in a queue based on their arrival time. The process that arrives first gets executed first. Execution Order : Processes are executed in the order they arrive. The process at the front of the queue is selected for execution. Advantages: Easy to implement. Minimal overhead. Disadvantages: Often results in long waiting times. Leads to the convoy effect (where a long process holds up other processes). Sh...

Banker's Algorithm- Deadlock Detection

The Banker's Algorithm is a deadlock avoidance algorithm used in operating systems to prevent deadlocks in a system with limited resources. It was developed by Edsger Dijkstra in 1965. The algorithm ensures that the system will allocate resources in such a way that it will avoid deadlock, even if resources are requested in an arbitrary order. Let's break down the Banker's Algorithm into steps: 1. System Initialization: At the beginning, the system must know the total number of resources of each type and the maximum demand of each process. It also needs to keep track of the currently available resources of each type. 2. Allocation: When a process requests resources, the system must check if granting those resources would put it in an unsafe state (i.e., could potentially lead to a deadlock). If the request can be granted without causing an unsafe state, the resources are allocated. Otherwise, the process must wait until the requested resources can be safely allocated. Safety...
