====== Removing a Node From a List ======


----

You can remove the first node, the last node, or a specific node from a list. The following sections explain how to do it.

===== Removing the First Node =====

To remove the first node from a list, use the ''%%RemHead()%%'' function:

''%%Node *RemHead( List *l )%%''\\


The ''%%l%%'' argument is a pointer to the list from which you want to remove the node. The function returns a pointer to the node that was removed from the list or NULL if the list was empty.

===== Removing the Last Node =====

To remove the last node from a list, use the ''%%RemTail()%%'' function:

''%%Node *RemTail( List *l )%%''\\


The ''%%l%%'' argument is a pointer to the list from which you want to remove the node. The function returns a pointer to the node that was removed from the list or NULL if the list was empty.

===== Removing a Specific Node =====

To remove a specific node from a list, use the ''%%RemNode()%%'' function:

''%%void RemNode( Node *n )%%''\\


The ''%%n%%'' argument is a pointer to the node you want to remove. Because a node can be only in one list, the node is automatically removed from the correct list.
