CFileTime::operator <

  • 项目

This operator compares two CFileTime objects to determine the lesser.

bool operator<( 
   CFileTime ft  
) const throw( );

Parameters

  • ft
    The CFileTime object to be compared.

Return Value

Returns true if the first object is less (earlier in time) than the second, false otherwise.

Example

// Test for one time less than another
// Declare the CFileType objects
CFileTime myFT1, myFT2;

// Obtain the first time value
myFT1 = CFileTime::GetCurrentTime();

// Pause for a moment...
Sleep(1000);

// Obtain the second time value
myFT2 = CFileTime::GetCurrentTime();

// Perform the comparison
if (myFT1 < myFT2)
   _tprintf_s(_T("Time is going in the correct direction.\n"));
else
   _tprintf_s(_T("Oh dear. Time is going backwards.\n"));
