Programming This forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

help needed here...


why it never reach the second thread?
=============================================
#include<stdio.h>
#include<stdlib.h>
#include<pthread.h>

void fireInTheHole(void);
static int accnt1, accnt2;

int main(){
accnt1=0;
accnt2=0;

pthread_t thread1, thread2;
pthread_create(&thread1, NULL, (void*)fireInTheHole, NULL);
pthread_create(&thread2, NULL, (void*)fireInTheHole, NULL);

printf("Thread join\n:");
pthread_join(thread1, NULL);
pthread_join(thread2, NULL);

return 0;
}

void fireInTheHole(){
int counter = 0;
int tmp1, tmp2, r;
do {
tmp1 = accnt1;
tmp2 = accnt2;
r = rand();
accnt1 = tmp1 + r;
accnt2 = tmp2 - r;
counter ++;
} while (accnt1 + accnt2 == 0);

printf("Stopped w/ counter value: %d\n", counter);
printf("accnt1 = %d\naccnt2 = %d\n", accnt1,accnt2);
}
=============================================
