CObList::GetAt

  • 아티클

A variable of type POSITION is a key for the list.

CObject*& GetAt(
   POSITION position 
);
const CObject*& GetAt( 
   POSITION position  
) const;

Parameters

  • position
    A POSITION value returned by a previous GetHeadPosition or Find member function call.

Return Value

See the return value description for GetHead.

Remarks

It is not the same as an index, and you cannot operate on a POSITION value yourself. GetAt retrieves the CObject pointer associated with a given position.

You must ensure that your POSITION value represents a valid position in the list. If it is invalid, then the Debug version of the Microsoft Foundation Class Library asserts.
