	)

Clone a IOBufferBlock chain.

Used to snarf a IOBufferBlock chain w/o copy.

Parameters:

	b	head of source IOBufferBlock chain.
	offset	# bytes in the beginning to skip.
	len	bytes to copy from source.

Returns:: ptr to head of new IOBufferBlock chain.

	)

Skip over specified bytes in chain.

Used for dropping references.

Parameters:

	b	head of source IOBufferBlock chain.
	poffset	originally offset in b, finally offset in returned IOBufferBlock.
	plen	value of write is subtracted from plen in the function.
	write	bytes to skip.
