Although much work has apparently gone into providing support for manipulation binary data I was unable to uncover a Haskell equivalent of the C fgetc and fputc functions. The Haskell equivalents work with Unicode character streams, not bytes words etcetera. I did find a library for handling arrays of bytes and such, but I did not find it to be convenient for the application I have in mind. I resolved myself to emitted Unicode 0s and 1s that are later converted to binary 0s and 1s by means of a C program. Is this functionality missing in Haskell? or did I miss something?
It is not in the Standard, but (at least) GHC has hPutBuf and hGetBuf (see http://haskell.org/ghc/docs/latest/html/libraries/base/System-IO.html). Cheers Ben
