HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) |
Return valueFurther information
The function F_VN_IncrementIterator increments an iterator by one element. If instead of that you wish to decrement the iterator or to increment it by several positions, use the function F_VN_AdvanceIterator.
Parameter
Iterator
The parameter ipIterator is of the type ITcVnForwardIterator. Since ITcVnBidirectionalIterator and ITcVnRandomAccessIterator inherit from it, these can also be transferred to the function. If a forward iterator is to be decremented, an internal attempt is made to transform it into a bidirectional iterator and to decrement it.
