I figured out one solution.  as it turns out, it was an address.  So my 
solution is.


function encrypt_textarea_0()
    object address
    integer len
    integer start
    sequence s

    start =0
    len = gtk_text_get_length(txt)
    address=gtk_editable_get_chars(txt,start,len)
    s=peek({address,len})


    printf(1,"%s",{s})
    return NULL
end function
constant encrypt_textarea=call_back(routine_id("encrypt_textarea_0"))

I'm not sure it's how the lib was intended to be used, but it seems to 
work.
