multithread on AIX

I'd like to have an example of using multithread on AIX 4.  The example only need to create another thread and run it.

Please also include the make file.

Doesn't AIX support POSIX threads?

The following code segment starts two similar threads, waits for their completion and then terminates.  Cut the code segment and paste in a file, say 't.c'.  Compile using the following command
     cc_r t.c -o t -lpthreads

-- code segment start --
#include <pthread.h>
#include <stdio.h>

#define COUNT   (INT_MAX/10)

void *FirstThread(void *v)
{
        int i = 0;

        printf("Thread one started\n");
        while ( i < COUNT )
                i++;
        printf("Thread one done - %d\n",i);
        pthread_exit(&i);
}
void *SecondThread(void *v)
{
        int i = 0;
        printf("Thread two started\n");
        while ( i < COUNT )
                i++;
        printf("Thread two done - %d\n",i);
        pthread_exit(&i);
}
main()
{
        pthread_t t1, t2;
        pthread_attr_t attr;
        int i;

        if ( pthread_attr_init(&attr) )
                perror("attr init");

/* Create a attached thread, so that we can wait for its completion */
        if (  pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_UNDETACHED) )
                perror("set detach");

        if ( pthread_create(&t1, &attr, FirstThread, NULL) )
                perror("thread create failed");
        if ( pthread_create(&t2, &attr, SecondThread, NULL) )
                perror("thread create failed");

/* wait for threads to complete */
        pthread_join(t1, NULL);
        printf("Thread one completed\n");
        pthread_join(t2, NULL);
        printf("Thread two completed\n");
}

Thanks a lot.  One more question: what is the difference between cc and cc_r?

I *think* cc_r links with thread safe libraries and generates re-entrant code.
