Detailed Description

Platform-specific utils.

This class provides system-specific utilities like displaying user dialogs and querying system timers for exact timestamps.

Member Function Documentation

float CSystemUtils::TimeStampDiff ( SystemTimeStamp before,
SystemTimeStamp after,
SystemTimeUnit  unit = STU_SEC 
)

Returns a difference between two timestamps in given time unit.

The difference is after - before.

virtual long long CSystemUtils::TimeStampExactDiff ( SystemTimeStamp before,
SystemTimeStamp after 
)
pure virtual

Returns the exact (in nanosecond units) difference between two timestamps.

The difference is after - before.

Implemented in CSystemUtilsOther, CSystemUtilsLinux, and CSystemUtilsWindows.
