AddBefore ( TDblQueLinkBase * )

IMPORT_C void

AddBefore

(

TDblQueLinkBase *

aLink

)

Inserts this link object before the specified link object.

The specified link object must already be in the doubly linked list.

The function cannot be used to insert a list element into the beginning or end of a doubly linked list; this is handled by the TDblQue::AddFirst() and TDblQue::AddLast() functions.

Parameters
aLink	A pointer to the link object embedded within the list element to which this link object is to be connected. It must not be NULL.

Enque ( TDblQueLinkBase * )

IMPORT_C void

Enque

(

TDblQueLinkBase *

aLink

)

Inserts this link object after the specified link object.

The specified link object must already be in the doubly linked list.

The function cannot be used to insert a list element into the beginning or end of a doubly linked list; this is handled by the TDblQue::AddFirst() and TDblQue::AddLast() functions.
