passing Strings with FFI

[Corneliu Popeea]

Hello,

I want to pass a String to a function which is imported from C code:
	foreign import  "pass" prim_pass :: String -> String
The declaration above gives me an error from ghc like "String type not 
supported for imported functions".
I thought that String being [Char] should be supported (somehow like a 
definition with "newtype" keyword).
Can you tell me how can I pass strings to and from C code, as simple as 
possible (I know about HDirect, but I couldn't make it work for me: red-hat 
7.1, ghc 5.00)?

Best regards,
Corneliu
