41 *#* Revision 1.4 2006/07/19 12:56:26 bernie
42 *#* Convert to new Doxygen style.
44 *#* Revision 1.3 2006/02/21 21:28:02 bernie
45 *#* New time handling based on TIMER_TICKS_PER_SEC to support slow timers with ticks longer than 1ms.
47 *#* Revision 1.2 2005/11/27 03:58:18 bernie
48 *#* Add POSIX timer emulator.
50 *#* Revision 1.1 2005/11/27 03:04:08 bernie
51 *#* Move test code to timer_test.c; Add OS_HOSTED support.
