Re: 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.

Note that GHC supports sockets directly, via the Network (high-level) and Network.Socket (low-level) modules.

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?

GHC has an interface to the POSIX I/O API (i.e. descriptors) in System.Posix.IO. -- Glynn Clements
