Parameters:

	fd	[in] file descriptor
	data	[out] buffer to store the read data
	len	[out] received length in bytes
	maxlen	[in] maximum length of data buffer in bytes

Returns:

received data length in bytes, or -1 on error.

		int	len
	)

Write a data segment to a network stream.

Parameters:

	fd	[in] file descriptor
	data	[in] buffer that holds data to write
	len	[out] received length in bytes

Returns:

actually written data length in bytes, or -1 on error.
