<dd><p>Set current number of background processes for parcellfun.
</p>
<p>The number of used background processes is determined by the first argument
to <code>parcellfun</code>. If necessary, <code>parcellfun</code> will spawn new
background processes, but it will never remove any of them, even if it
does not use all of them.
<code>parcellfun_set_nproc</code> can be used to set the number of currently spawned
processes to <var>nproc_arg</var>. This may be used to remove all background
processes between calls to <code>parcellfun</code> by specifying an <var>nproc_arg</var>
of zero.
</p>
<p>The real number of spawned processes will be limited to the available
processor cores and is returned.
