>Description:
This is code from /usr/src/lib/libc_r/uthread/uthread_attr_setscope.c :

int
pthread_attr_setscope(pthread_attr_t *attr, int contentionscope)
{
        int ret = 0;

        if ((attr == NULL) || (*attr == NULL)) {
                /* Return an invalid argument: */
                ret = EINVAL;
>How-To-Repeat:

 >>        } else if ((contentionscope != PTHREAD_SCOPE_PROCESS) ||
 >>            (contentionscope != PTHREAD_SCOPE_SYSTEM)) {
                 /* We don't support PTHREAD_SCOPE_SYSTEM. */
                 ret = ENOTSUP;
         } else
                 (*attr)->flags |= contentionscope;
 
         return(ret);
 }
 
 Since PTHREAD_SCOPE_PROCESS != PTHREAD_SCOPE_SYSTEM, this function 
 always fails.
