From 4e3664f22b39c3efa33f5778a651a083b5e1f544 Mon Sep 17 00:00:00 2001 From: David Zeuthen Date: Sun, 8 Nov 2009 12:25:55 -0500 Subject: [PATCH] gudev: Fix up GUdevDeviceNumber Actually dev_t is an unsigned quad type (e.g. 64-bit even on 32-bit x86) so defining it to be an integer is wrong and not future proof. Thus, redefine it to actually be a dev_t (as originally wanted) and instead add a work-around for GNOME bug #584517, see https://bugzilla.gnome.org/show_bug.cgi?id=584517 for details. This way, GObject Introspection will still work. This change is technically an API/ABI break but - all released GUdev versions requires the user to understand that the API/ABI is unstable by requiring the G_UDEV_API_IS_SUBJECT_TO_CHANGE symbols to be defined - functions using GUdevDeviceNumber are rarely used so we don't bump the so number.
