Function Documentation

void* LL_getPayload (  LL_node *  head, unsigned int  uid )

Find the payload corresponding to a give id. Parameters: head  Pointer to the start of the linked list uid  Unique ID Returns: Pointer to payload associated with id

int LL_isPresent (  LL_node *  head, unsigned int  uid )

Check if any node on the list contains this id. Parameters: head  Pointer to the start of the linked list uid  Unique ID Returns: 1 If there is a node on the list with this id 0 If no node has this id

int LL_registerNode (  LL_node *  head, unsigned int  uid, void *  pay )

Create an association between the uid and the pay pointer. Parameters: head  Pointer to the start of the list of LL handlers uid  Unique id for this node pay  Pointer to the void structure used for all datagrams for this LL Return values: 1  If the attempt to register a new handler failed because a handler with that ID already exists; use replace. -1  If the attempt to register a new handler failed because of a memory allocation error 0  The new handler was successfully registered

void* LL_unregisterNode (  LL_node *  head, unsigned int  uid )

Remove an id from the list of handled ids (NO-OP if no node on the list has this id). Parameters: head  Pointer to the start of the list of LL handlers uid  Unique id for the node to remove Returns: Pointer to the payload of the unregistered node, or NULL if the node does not exist
