i.e. user-defined functors must not throw exceptions.
Also, the order of execution is not guaranteed for some functions, of course.
Therefore, user-defined functors should not have any concurrent side effects.
OpenMP parallel regions in concurrent threads,
it is not possible to call parallel STL algorithm in
concurrent threads, either.
-It might work with other compilers, though.</p></div><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td align="left"><a accesskey="p" href="parallel_mode.html">Prev</a> </td><td align="center"><a accesskey="u" href="parallel_mode.html">Up</a></td><td align="right"> <a accesskey="n" href="bk01pt03ch18s03.html">Next</a></td></tr><tr><td align="left" valign="top">Chapter 18.
