CObList::FindIndex

POSITION FindIndex( int nIndex ) const;

Return Value

A POSITION value that can be used for iteration or object pointer retrieval; NULL if nIndex is too large. (The framework generates an assertion if nIndex is negative.)

Parameters

nIndex

The zero-based index of the list element to be found.

Remarks

Uses the value of nIndex as an index into the list. It starts a sequential scan from the head of the list, stopping on the nth element.

Example

See CObList::CObList for a listing of the CAge class.

CObList list;
POSITION pos;

list.AddHead( new CAge( 21 ) );
list.AddHead( new CAge( 40 ) ); // List now contains (40, 21).
if( ( pos = list.FindIndex( 0 )) != NULL )
{
    ASSERT( *(CAge*) list.GetAt( pos ) == CAge( 40 ) );
}
