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);

Call stop.

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.

Giving unique ACE scoped names for some important

RTSignal-Related constants. Becuase sometimes, different platforms use different names for these constants.
