Write a C program to simulate the following IPC problem Make

Write a C program to simulate the following IPC problem. Make sure to use semaphores to synchronize the processes/threads.

Fraternity Party

  A group of fraternity brother and sorority sisters is having a party and drinking from a large communal keg that can hold N servings of soda. When a partier wants to drink, he or she fills a cup from keg, unless it is empty. If the keg is empty, the partier wakes up the pledge and then waits until the pledge has returned with a new keg.

Solution

IPC: Inter process Communication.

Program:

#include<stdio.h>

#include<unistb.h>

#include<stdlib.h>

#include<string.h>

#include<pthread.h>

#include<semaphore.h>

/ the above functions are predefined functions which are required in our program /

void * thread_function(void *arg);

sem_f bin_sem;

#define party_size 1024

/ definition function /

char party_area[party_size];

int main()

{

int result;

pthread_f a_thread;

void *thread_result;

result= sem_init(&bin_sem,0,0);

{

if (result != 0)

{

perror(\" the partier waits for the pledge\");

exit(exit_failure);

}

printf(\" the drink is not filled with keg\");

if(result != 0)

{

perror(\" the partier wake sup the pledge\");

exit(exit_success);

}

printf(\" the drink is filled with the new keg\");

sem_wait (&bin_sem);

}

pthread_exit(null);

}
