The glib structure GTimeVal itself is equivalent to struct timeval, which is returned by the gettimeofday() UNIX call. Additionally this wrapper provides an assortment of time manipulation functions. Constructor & Destructor Documentation Glib::TimeVal::TimeVal (   )  [inline] Glib::TimeVal::TimeVal ( long    seconds, long    microseconds )  [inline] Glib::TimeVal::TimeVal ( const GTimeVal&    gtimeval )  [inline] Member Function Documentation void Glib::TimeVal::add ( const TimeVal&    rhs )  void Glib::TimeVal::add_microseconds ( long    microseconds )  void Glib::TimeVal::add_milliseconds ( long    milliseconds )  void Glib::TimeVal::add_seconds ( long    seconds )  double Glib::TimeVal::as_double (   )  const [inline]   Returns a double representation of the time interval. This member function converts the time interval, that is internally stored as two long values for seconds and microseconds, to a double representation, whose unit is seconds. void Glib::TimeVal::assign_current_time (   )    Assigns the current time to the TimeVal instance. Equivalent to the UNIX gettimeofday() function, but is portable and works also on Win32. bool Glib::TimeVal::negative (   )  const [inline] TimeVal& Glib::TimeVal::operator+= ( long    seconds )  [inline] TimeVal& Glib::TimeVal::operator+= ( const TimeVal&    gtimeval )  [inline] TimeVal& Glib::TimeVal::operator-= ( long    seconds )  [inline] TimeVal& Glib::TimeVal::operator-= ( const TimeVal&    gtimeval )  [inline] TimeVal& Glib::TimeVal::operator= ( const GTimeVal&    gtimeval )  [inline] void Glib::TimeVal::subtract ( const TimeVal&    rhs )  void Glib::TimeVal::subtract_microseconds ( long    microseconds )  void Glib::TimeVal::subtract_milliseconds ( long    milliseconds )  void Glib::TimeVal::subtract_seconds ( long    seconds )  bool Glib::TimeVal::valid (   )  const [inline]   Checks whether the stored time interval is positive. Returns true if the stored time / time interval is positive.
