CObList::FindIndex

Uses the value of nIndex as an index into the list.

POSITION FindIndex(
   INT_PTR nIndex 
) const;
nIndex

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

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.)

It starts a sequential scan from the head of the list, stopping on the nth element.
