CObList::FindIndex
Uses the value of nIndex as an index into the list.
POSITION FindIndex(
INT_PTR nIndex
) const;
Parameters
- nIndex
The zero-based index of the list element to be found.
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.)
Remarks
It starts a sequential scan from the head of the list, stopping on the nth element.

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));
