Function findNode
findNode -- find a node by name
LinkedList!(va_toolbox.linked_list.LinkListHeadExtras,va_toolbox.linked_list.LinkListNodeExtras)* findNode
(
LinkedList!(va_toolbox.linked_list.LinkListHeadExtras,va_toolbox.linked_list.LinkListNodeExtras)* list,
string name
);
Traverse a system list until a node with the given name is found. To find multiple occurrences of a string, this function may be called with a node starting point.
No arbitration is done for access to the list! If multiple tasks access the same list, an arbitration mechanism such as Semaphores must be used.
Parameters
| Name | Description |
|---|---|
| list | a pointer to the target list header |
| name | a pointer to a name string terminated with null |
Returns
A pointer to the node with the same name, else null to indicate that the string was not found.
Example
ListNode* myNode; ... if ( myNode = myList.findNode("FooBar" )) { ... }
Notes
This function does not arbitrate for access to the list. The calling task must be the owner of the involved list.
