use the foreign import mechanism to make BZ2_bzopen, BZ2_bzwrite and BZ2_bzclose available in your program.
bzlib and zlib wrappers are available in <http://www.sourceforge.net/projects/qforeign/> (for ghc >= 4.08 and nhc98 >= 1.02).
bzlib does not have this problem: its in-memory compressed data is identical to .bz2 file contents.
Both wrappres include functions for lazy compression and decompression of strings (String -> String).
The wrapper works fine, except for - when bunzipping a file - bunzip complains like this: bunzip: wbg-5-11-0.xml.bz2: trailing garbage after EOF ignored Indeed, the file produced by the Haskell program is one byte longer than the file produced by bzip (called from the command line). Michael
