CList::GetAt

  • 项目

TYPE**&GetAt(POSITIONposition);**

TYPEGetAt(POSITIONposition**)const;**

Return Value

See the return value description for GetHead.

Parameters

TYPE

Template parameter specifying the type of object in the list.

position

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

Remarks

A variable of type POSITION is a key for the list. It is not the same as an index, and you cannot operate on a POSITION value yourself. GetAt returns the element (or a reference to the element) 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.

Example

See the example for CList::GetHeadPosition.
