_SC_NPROCESSORS_ONLN on Dragonfly

[Klaus Heinz]

Hi,

I am feeding back patches to the authors of audio/gtkpod and found this
one (in patch-bj) concerning Dragonfly:

       {   /* set to maximum available number of processors */
  +#if defined(_SC_NPROCESSORS_ONLN) && !defined(__DragonFly__)
          conv->max_threads_num = sysconf (_SC_NPROCESSORS_ONLN);
  +#else
  +       conv->max_threads_num = 1;
  +#endif
          /* paranoia mode on */
          if (conv->max_threads_num <= 0)
          {

A little research showed that _SC_NPROCESSORS_ONLN was added to
Dragonfly in February. If this is really working the above could be
simplified to

  +#if defined(_SC_NPROCESSORS_ONLN)
          conv->max_threads_num = sysconf (_SC_NPROCESSORS_ONLN);
  +#else
  ...

Is there a reason to set the number of threads to 1 on Dragonfly systems
where _SC_NPROCESSORS_ONLN is defined?

ciao
