how to open a file descriptor

Hello. I'm in the process of interfacing with some C code (libcurl), and I thought that the easiest way to transfer the data in (which is a file transfered over the network) would be to open a pipe and write it into the pipe, and then to pass the pipe over to haskell where I could read it with the IO monad normally. Is there any nice way to open up a file descriptor? I was looking at the ghc internal code, which has an openFd function that would do what I want, but it doesn't seem to be exported. :( Any ideas? -- David Roundy http://civet.berkeley.edu/droundy/
