Re: [Haskell-cafe] How to return a network connection to C

If I understand you correctly you need a StablePtr to your Connection value. Please see: http://www.haskell.org/ghc/docs/latest/html/libraries/base-4.6.0.1/Foreign-S... Best regards, Krzysztof Skrzętnicki On Thu, Feb 28, 2013 at 6:31 PM, C K Kashyap wrote:

I am using http://hackage.haskell.org/package/connection. So I create network connection in Haskell

getConnection :: IO Connection

I'd like this connection to be returned to C so that subsequent calls from C can send in the connection handle.

What data type are you dealing with exactly?

If you have a socket, I guess you can just use it from C (via FFI).

PS: By "Network.Connection", do you mean http://hackage.haskell.org/package/network-connection-0.1.1 ? Seems deprecated.

Hi, I am using Network.Connection to connect to gmail in my Haskell module - that's compiled to DLL and invoked from C.

I need a mechanism to return the connection handle to C so that it can pass it in the subsequent calls. How can I achieve this?
