TpHeap * tp_heap_new (GCompareFunc comparator,GDestroyNotify destructor);
|
Comparator by which to order the pointers in the heap |
|
Function to call on the pointers when the heap is destroyed
or cleared, or NULL if this is not needed
|
Returns : |
A new, empty heap queue. |
void tp_heap_destroy (TpHeap *heap);
Destroy a TpHeap. The destructor, if any, is called on all items.
|
The heap queue |
void tp_heap_clear (TpHeap *heap);
Remove all items from a TpHeap. The destructor, if any, is called on all items.
|
The heap queue |
void tp_heap_add (TpHeap *heap,gpointer element);
Add element to the heap queue, maintaining correct order.
|
The heap queue |
|
An element |
void tp_heap_remove (TpHeap *heap,gpointer element);
Remove element from heap, if it's present. The destructor, if any,
is not called.
|
The heap queue |
|
An element in the heap |
gpointer tp_heap_peek_first (TpHeap *heap);
|
The heap queue |
Returns : |
The first item in the queue, or NULL if the queue is empty
|
gpointer tp_heap_extract_first (TpHeap *heap);
Remove and return the first element in the queue. The destructor, if any, is not called.
