skb_seq_read — Sequentially read skb data
unsigned int skb_seq_read ( | unsigned int | consumed, |
| const u8 ** | data, | |
| struct skb_seq_state * | st); |
consumednumber of bytes consumed by the caller so far
datadestination pointer for data to be returned
ststate variable
Reads a block of skb data at &consumed relative to the
lower offset specified to skb_prepare_seq_read. Assigns
the head of the data block to &data and returns the length
of the block or 0 if the end of the skb data or the upper
offset has been reached.
The caller is not required to consume all of the data
returned, i.e. &consumed is typically set to the number
of bytes already consumed and the next call to
skb_seq_read will return the remaining part of the block.
