thread_c.c

#include <pthread.h>

void *work(void *arg) { /* implementation */ }

int main() {
    pthread_t t1, t2;

    int magic_nr_1 = 46;
    int magic_nr_2 = 3;

    pthread_create(&t1, NULL, thread, (void *) magic_nr_1);
    pthread_create(&t2, NULL, thread, (void *) magic_nr_2);

    pthread_join(t1,NULL);
    pthread_join(t2,NULL);
}

I've updated this with a trivial impl that will actually compile and run :) The two most important changes, though, are in 's/thread/work/' for the parameter name in pthread_create, and taking the address of magic_nr_* before casting to void*:
