PThreads Typo???

gistfile1.c

void hello(int *n)
{
    printf("hello %d\n",*n);
}

int main(void)
{
    int m;
    pthread_t thr1, thr2;
    
    m = 1;
    pthread_create(&thr1, NULL, (void*(*)(void*))hello, &m);
    m = 2;
    pthread_create(&thr1, NULL, (void*(*)(void*))hello, &m);

    return 0;
}
