struct list_head

[Sridhar N <srin@symonds.net>]

Hi,
	I need a to use a singly-linked list in my program, and since a 
doubly-linked list is provided in linux/list.h, i thought of using it.  But i 
don't know how to use it.  I have a structure of nodes that i want to link, 
say

struct foo {
	int foo1;
	int foo2;
	char * foo3;
	struct list_head list;
};

How do I add a new node or initialize it. Seeing list.h didn't help me :-(
But why doesn't task_struct use it ?

regards
Sridhar
