CTimeSpan::CTimeSpan
CTimeSpan();
CTimeSpan(constCTimeSpan&timeSpanSrc);
CTimeSpan(time_ttime**);**
CTimeSpan(LONGlDays**,intnHours,intnMins,intnSecs);**
Parameters
timeSpanSrc
A CTimeSpan object that already exists.
time
A time_t time value.
lDays, nHours, nMins, nSecs
Days, hours, minutes, and seconds, respectively.
Remarks
All these constructors create a new CTimeSpan object initialized with the specified relative time. Each constructor is described below:
CTimeSpan( ); Constructs an uninitialized CTimeSpan object.
CTimeSpan( const CTimeSpan& ); Constructs a CTimeSpan object from another CTimeSpan value.
CTimeSpan( time_t ); Constructs a CTimeSpan object from a time_t type. This value should be the difference between two absolute time_t values.
CTimeSpan( LONG, int, int, int ); Constructs a CTimeSpan object from components with each component constrained to the following ranges:
Component Range lDays 0–25,000 (approximately) nHours 0–23 nMins 0–59 nSecs 0–59
Note that the Debug version of the Microsoft Foundation Class Library asserts if one or more of the time-day components is out of range. It is your responsibility to validate the arguments prior to calling.
Example
// example for CTimeSpan::CTimeSpan
CTimeSpan ts1; // Uninitialized time value
CTimeSpan ts2a( ts1 ); // Copy constructor
CTimeSpan ts2b = ts1; // Copy constructor again
CTimeSpan ts3( 100 ); // 100 seconds
CTimeSpan ts4( 0, 1, 5, 12 ); // 1 hour, 5 minutes, and 12 seconds
