NAME
ACE_Countdown_Time -
Keeps track of the amount of elapsed time.
SYNOPSIS
#include <ace/OS.h>
class ACE_Countdown_Time
{
public:
ACE_Countdown_Time (ACE_Time_Value *max_wait_time);
~ACE_Countdown_Time (void);
int start (void);
int stop (void);
int update (void);
private: ACE_Time_Value *max_wait_time_;
ACE_Time_Value start_time_;
int stopped_;
};
DESCRIPTION
This class has a side-effect on the max_wait_time
-- every
time the stop
method is called the max_wait_time
is
updated.
Initialization and termination methods.
ACE_Countdown_Time (ACE_Time_Value *max_wait_time);
Cache the max_wait_time
and call start
.
~ACE_Countdown_Time (void);
int start (void);
Cache the current time and enter a start state.
int stop (void);
Subtract the elapsed time from max_wait_time_ and enter a stopped
state.
int update (void);
Calls stop and then start. max_wait_time_ is modified by the
call to stop.
private: ACE_Time_Value *max_wait_time_;
Maximum time we were willing to wait.
ACE_Time_Value start_time_;
Beginning of the start time.
int stopped_;
Keeps track of whether we've already been stopped.

The ACE_Sched_Priority type should be used for platform-
independent thread and process priorities, by convention.
int should be used for OS-specific priorities.
typedef for the _stat data structure
Giving unique ACE scoped names for some important
RTSignal-Related constants. Becuase sometimes, different
platforms use different names for these constants.
