I was wondering if anyone here has a solution for writing binary files that works in hugs and ghc that doesn't require getting libs.
I dont' know exactly about the current status of Hugs' libs, but I fear the answer to your question is "no".
I looked at this page: http://haskell.cs.yale.edu/ghc/docs/latest/set/sec-ioexts.html [...]
... and that was exactly the right place, see section "Bulk transfers": (http://haskell.cs.yale.edu/ghc/docs/latest/set/sec-ioexts.html#SEC-BULK-TRAN...)
hGetBuf :: Handle -> Addr -> Int -> IO Int hGetBufFull :: Handle -> Addr -> Int -> IO Int
hPutBuf :: Handle -> Addr -> Int -> IO Int hPutBufFull :: Handle -> Addr -> Int -> IO ()
These action read/write a given amount of bytes to/from a buffer. There hasn't been much consensus about a higher level interface yet, but you can have a look at my variant sitting on top of this:
I saw this part but I couldn't figure out how I was supposed to open a file and use these functions. So maybe I was looking for an example. I want to try to write a compiler for some language in haskell, but I don't know how to write binary files... It looks like I use openFileEx but I can't get anything to compile without seeing an example of it. Thanks for the reply.
