void tn_c_lzw_filestream::writedata	(	const void *	buf,
		int	size
	)			[virtual]

writes data to the stream

Parameters:

	buf	pointer to the buffer
	size	the number of bytes which are going to be written

Implements tnstream.

int tn_c_lzw_filestream::readdata	(	void *	buf,
		int	size,
		bool	excpt = true
	)			[virtual]

Reads data from the stream.

Parameters:

	buf	the buffer which the data is written to
	size	the number of bytes which should be read
	excpt	If true the operation will throw an exception if the desired number of bytes cannot be read.

Returns:

the number of bytes which were read.
