Heh, you cant do that :)

A FILE pointer and an integer file desctiptor is not the same thing,
on some (most) systems; you will be able to do:
    g_io_channel_unix_new(mem_dump->_fileno)

But it would be better if you just did g_io_channel_new_file() ;-)
(if for some reason, you must use an fd; dont use fopen, use g_open
with the unix `open' syntax instead, I think its somwhat less portable
though).

Cheeers,
