I want to group them with Network functions because traditionally these specific functions *are* in networking packages.

I agree. It is true that these functions are in the header on my machine. The ntoh* and hton* are just data manipulation, just as Network.URI is all about constructing and manipulating URI data. The question I think we should answer is: Do we wish to follow the precedent of putting URI under Network and not Data? Pragmatically, programmers will expect to find these functions near the 'net ones. A "network-byteorder" package which has the "Network.ByteOrder" module is the most flexible thing to create. It can be updated and reinstalled independently of the "network" package.

On *nix systems, the prototypes reside in . On Windows they reside in and one must link against libws2_32.

The package I have locally supports all platforms. It just does a foreign import of the function (and uses a preprocessor definition to pick the calling convention).

One could make an argument to add these sorts of functions to Word and Int packages.

Are these going to be available on Windows or just Posix systems?

And these are NOT performing network communication. They are bit manipulations.

I could imagine putting them in/under the Data.Word or Data.Bits more than Network.*

And they should also be made to work with the corresponding Foreign.C.Types of CShort, etc.

While working on a project, I discovered that hton[sl] and ntoh[sl] are missing from the networking libraries. It appears there was some justification for this, but I've fallen upon a few instances where things were *not* working as expected. (Specifically when newtype'ing around HostAddress.)

As such, I'm putting together a few extra functions that I think should exist in Network somewhere. I'm calling the package Network.Util (but am open to changes).

Currently this only has:

* htons * htonl * ntohs * ntohl

Before I drop this on hackage:

1. Is there a reason I shouldn't do this? 2. Are there other suggestions for missing functions? (preferably

cross-platform suggestions)

Thanks all.
