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.

Glib::TimeVal::TimeVal | ( | const GTimeVal& | gtimeval | ) | [inline] |
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.

TimeVal& Glib::TimeVal::operator-= | ( | long | seconds | ) | [inline] |
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.
bool Glib::TimeVal::negative | ( | ) | const [inline] |
bool Glib::TimeVal::valid | ( | ) | const [inline] |
Checks whether the stored time interval is positive.
Returns true if the stored time / time interval is positive.
