 *
 * $Log$
 * Revision 1.5  2009/01/17 11:26:46  haraldkipp
 * Getting rid of two remaining BSD types in favor of stdint.
 * Replaced 'u_int' by 'unsinged int' and 'uptr_t' by 'uintptr_t'.
 *
 * Revision 1.4  2008/08/11 06:59:41  haraldkipp
 * BSD types replaced by stdint types (feature request #1282721).
 *
 * Revision 1.3  2006/01/23 17:32:11  haraldkipp
 * Avoid hang-ups caused by debug leftovers.
 *
 * Revision 1.2  2006/01/05 16:51:06  haraldkipp
 * Several new functions added to query and modify the clock settings.
 *
 * Revision 1.1  2005/10/24 10:21:57  haraldkipp
 * Initial check in.
