 Oi Murilo - Todo bom ?

gchar*      g_locale_to_utf8                (const gchar *opsysstring,
                                             gssize len,
                                             gsize *bytes_read,
                                             gsize *bytes_written,
                                             GError **error);

http://developer.gnome.org/doc/API/2.0/glib/glib-Character-Set-Conversion.html#g-locale-to-utf8

  -- You have to pass all of the above arguments:

  When passing GError, you need to do something like.

   GError  *error;

   g_locale_to_utf8( <the other args> , &error);

   Note that the function call will allocate the GError for you in case of a
error -- so, you MUST deallocate ( g_error_free(error)) if there was any error.

  Note also that GError is typedef,
  So, you do not have to do:
   struct GError *error .. just GError *error will do.

  ALL (at least the one I have seen) structs on gtk are typedef'ed, so there is
hardly a need to type the word struct when using glib/gtk

Hope this helps.
