I assume that the problem with the first one is that gettext might erroneously return a string containing % sequences, resulting in a runtime failure or even exploit. But that could also be a problem with the second one too, surely? (ie. gettext might return three or more % sequences). OCaml gettext offers two forms of the gettext function, one for plain strings and one for format strings[1]. The format string version checks that any % sequences in the translated string are compatible with those in the original string. (If not then the original string is returned to avoid any exploit). Sounds as if we need a similar feature in C gettext. A cursory check of the info file didn't show anything like this. Rich. [1] and of course the powerful type system ensures that you always use the correct form, ho hum ... -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines.
