◆ SetToFirst()
| IMPORT_C void TDblQueIterBase::SetToFirst | ( | ) |
Sets the iterator to point to the first element in the doubly linked list.
The function can be called to re-set the pointer at any time during the iterator's existence.
The function can be called even if the list has no elements.

◆ SetToLast()
| IMPORT_C void TDblQueIterBase::SetToLast | ( | ) |
Sets the iterator to point to the last element in the doubly linked list.
The function can be called to re-set the pointer at any time during the iterator's existence.
The function can be called even if the list has no elements.
