Hello El, Sunday, November 29, 2009, 8:00:02 PM, you wrote: segfault is due to free, you may omit peekCString call. you should free only memory that was malloced and not freed other way
Hello, I get a segfault when I do str <- peekCString ptr free ptr return (Just str)
But not when I don't free the C pointer. I also get the same behaviour with ByteString.packCString...
Could you please tell me if the memory is correctly freed by GHC when I don't do it myself? And how can I specify a custom free function (i.e. xmlFree function in libxml2)? Maybe I should use a data type with two fields : the String/ByteString and the ForeignPtr to the CString?
Regards
