Program of 2-thread for Linux Using the POSIX threads library. Once the thread spawning is done, the first thread should wait for user input

Posted By: Easy Tutor     Category: C Programming     Views: 1756

Using the POSIX threads library, write a 2-thread program for Linux. Once the thread spawning is done, the first thread (T1) should wait for user input. T1 should produce no output, but should shut down the whole process once the user types a q or a Q. T2 should take no input, but should generate a list of prime numbers starting at 2 and going as high as it can in the time allowed. From the user point of view, this program will generate primes until told to quit.

Code for Program of 2-thread for Linux Using the POSIX threads library. Once the thread spawning is done, the first thread should wait for user input in C Programming

# include <stdio.h>
# include <pthread.h>

void *t1(void *);

int main()
{
    pthread_t tid;
    int iCount,iNumber=2;
    int PrimeFlag=1;
    pthread_create(&tid,NULL,t1,NULL);
    for(;;)
    {
        for(iCount=2;iCount<iNumber;iCount++)
        {        
            if(iNumber % iCount==0)
            {
                PrimeFlag=0;
                break;
            }
        }        
        if(PrimeFlag==1)
        {
            printf("%d \t",iNumber);
        }
        PrimeFlag=1;
        iNumber++;
        if(iNumber % 10 ==0)
        {
            usleep(1);
        }

    }    
    return 0;
}

void *t1(void *p)
{
    char ch;
    while(1)
    {
        ch=getchar();
        if(ch=='q' || ch=='Q')
        {
            exit(0);

        }
    }
}
