[Haskell-cafe] Endian conversion

[Marc Ziegert]

for just making IO and a little bit-conversion, i would use c++ or even c. for such a problem you have to be near the machine, not necessarily near mathematical abstraction.
there exist assembler-commands to flip endians of register-values, so i would just search in /usr/include/*/* for a platform independent c-function, and either pipe a proxy through such a little prog, or patch an existing proxy, like "tinyproxy".
of course, if you want to make more than just a proxy, or if you want to play with different languages, be welcome to use haskell. but remind, it is not easy to use high-developed-mars-rover-technology to replace a shovel for playing with sand at the beach.
