I don't know, but here's a different suggestion, using
bzip2 (you could do the same with zlib for .gz files):
use the foreign import mechanism to make BZ2_bzopen,
BZ2_bzwrite and BZ2_bzclose available in your program.
do bz2 <- bzopen "output.bz2" "w"
let chars_to_write =3D ... :: String
bzwrite bz2 (packString chars_to_write) (length chars_to_write)
-- the above as many times as you like
and link your program with libbz2.a or libbz2.so.
Almost the same trick works with the zlib library for=20
directly reading/writing .gz files.
This strikes me as far more convenient than messing round
with pipes, etc.
