Detailed Description

Glib::TimeVal is a wrapper around the glib structure GTimeVal.

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.

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.

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.
