There are two nicer solutions (I have to explain this better in next 
version of the manual):
1) Give a member size to LZ_compress_open(). Then, every time 
LZ_compress_member_finished returns 1, call LZ_compress_restart_member.

2) Every time you want to start a new member, call LZ_compress_finish() 
and continue reading until LZ_compress_member_finished returns 1. Then 
call LZ_compress_restart_member (without closing the stream).

Take into account that perfect control is not possible because it is not 
possible to determine the exact size of a member in advance.
