CBaseList::Prev

  • 项目

Retrieves the previous position in the list.

POSITION Prev(
  POSITION pos
);

Parameters

  • pos
    Current position in the list.

Return Values

Returns a position cursor.

Remarks

This member function returns NULL when going past the end of the list. Calling the CBaseList::Prev member function with a null value is similar to calling the CBaseList::GetTailPositionI member function.

Use the CBaseList::GetI member function to return the object at the returned position.
