Sorry, wrong function, but still ... same as the condattr one...

int pthread_condattr_setpshared (pthread_condattr_t *attr
attribute_unused, int pshared)
{
  if (pshared != PTHREAD_PROCESS_PRIVATE && pshared !=
PTHREAD_PROCESS_SHARED)
    return EINVAL;

  /* For now it is not possible to shared a conditional variable.  */
  if (pshared != PTHREAD_PROCESS_PRIVATE)
    return ENOSYS;

  return 0;
}
