These functions build up information for the hardware layer,       and then all at once, pass it to the hardware layer. *************** REVISION HISTORY *********************************************   Date       Author      Reference   ========   ========    ==========================   99-11-10   bchoi       CR - CSGce39480                          Modify Audio Manager timer functionality to use SUAPI                          compliant timers.******************************************************************************/#include <audio/AM_Timers.H>#include <audio/AM_Event_Handler.H>#include <audio/am_server_task.h>#include <audio/AM_Tone_Sequence_Handler.H>extern AM_Event_Handler * am_event_handler;//===============================================================================// Function: Constructor//   Initialize all attributes of the class//===============================================================================AM_Timer_Base::AM_Timer_Base(){      Next         = NULL;    Prev         = NULL;    InitialDelay = 0;    Delay        = 0;    SeqIndex     = 0;    Active  = FALSE;}//===============================================================================// Function: Destructor////   - Does nothing the destructor does not need to be virtual, nothing//   //  //===============================================================================AM_Timer_Base::~AM_Timer_Base(){}//===============================================================================// Function:  StartSequence    //   -  This is the beginning of a sequence of timers, this will initialize//      the delay to the first value.
