Function Documentation

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

Get 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 the specified ID or NULL if the ID doesn't exist.

int LL_isPresent (  LL_node *  head, unsigned int  uid )

Check if an ID exists. This routine searches for a node with the given ID. Parameters: head  Pointer to the start of the linked list uid  Unique ID Return values: 1  If there is a node on the list with this ID Returns: 0 If no node has this ID

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

Create a node with a unique ID. This routine creates a node with the specified UID and payload. It is an error if a node with the ID already exists. Parameters: head  Pointer to the start of the list of LL handlers uid  Unique id for this node pay  Pointer to the payload. Return values: 0  The new node was successfully created 1  The ID already existed; use replace -1  Memory allocation failed

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

Remove the spcified node. This routine removes the node with the specified ID from a list, and returns its payload pointer. 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
