__skb_queue_head (9)

    NAME

    skb_queue_head - insert an sk_buff at the head of a list
     
    

    SYNOPSIS

    #include <linux/skbuff.h>
    void __skb_queue_head(struct sk_buff_head *list, struct sk_buff *newsk);
    void skb_queue_head(struct sk_buff_head *list, struct sk_buff *newsk);
     

    DESCRIPTION

    The skb_queue_head function adds newsk to the head of list. Specifically, it sets the list, next, and prev pointers in newsk, and increments the qlen element of list. It also rearranges the next and prev pointers in the existing head of list before returning.  

    RETURN VALUE

    None.  

    NOTES

    It is important to note the difference between not only __skb_queue_head and skb_queue_head, but all the __skb_ functions and their skb_ counterparts. Essentially, the __skb_ functions are non-atomic, and should only be used with interrupts disabled. As a convenience, the skb_ functions are provided, which perform interrupt disable / enable wrapper functionality in addition to performing their specific tasks.  

    AVAILABILITY

    Linux 1.0+
