Hi,
	Thanks for the reply. But what I need is to get each line for a
	.bz2 file recursively.

	I have done this easily with the zlib1g library by using the
	function gzgets which is very similar to fgets.

	But in libbz2, the only file reading function is:
		bzRead(&bzerror, bzFile, buf, 2048);

	where it reads 2048 bytes to buf regardless the newline
	character. And it would be too expensive to
	uncompress the whole file first and then start reading using
	standard libc functions.

	Thanks for the help in advance.

Regards,

Shao.
