Detailed Description
template<class Bottom = tool::bottom>
struct wpl::phy::timetracker< Bottom >
Microsecond-grained time tracker.
PHY headers have various fields that holds frames' arrival time on the medium. Some of them are only 32 bits long, thus wrapping every one hour and a half (roughly). This class tracks the evolution of such fields and maintains a microsecond count that does not wrap.
Just call the tick() method for every frames you get in your trace.

Constructor & Destructor Documentation
| wpl::phy::timetracker< B >::timetracker | ( | bool | force_pcap | ) | [inline] |
Default constructor - initialize the microsecond count to zero.
- Parameters:
-
[in] force_pcap If true, force the use of PCAP timestamps instead of PHY timestamps.
Member Function Documentation
| void wpl::phy::timetracker< B >::tick_tv | ( | const struct timeval & | tv | ) | [inline] |
Update the tracker with the given timeval structure.
This method assumes timeval structures never wrap around. A negative structure (tv_sec < 0) will yield valid but negative microsecond counts).
| void wpl::phy::timetracker< B >::tick_uint | ( | UIntType | ts | ) | [inline] |
Update the tracker with the given unsigned integer timestamp.
This method tracks wraparounds and maintains a consistent microsecond count.
