How to return a value from pthread threads in C?

Question

I\'am new to C and would like to play with threads a bit. I would like to return some value from a thread using pthread_exit()

My code is as follows:

Answer 1

You are returning a reference to ret which is a variable on the stack.

Answer 2

#include<stdio.h>
#include<pthread.h>
void* myprint(void *x)
{
 int k = *((int *)x);
 printf("\n Thread created.. value of k [%d]\n",k);
 //k =11;
 pthread_exit((void *)k);

}
int main()
{
 pthread_t th1;
 int x =5;
 int *y;
 pthread_create(&th1,NULL,myprint,(void*)&x);
 pthread_join(th1,(void*)&y);
 printf("\n Exit value is [%d]\n",y);
}
