22/* This file contains the legacy sync interface used by Android platform and
23 * device code. The direct contents will be removed over time as code
24 * transitions to using the updated interface in ndk/sync.h. When this file is
25 * empty other than the ndk/sync.h include, that file will be renamed to
26 * replace this one.
27 *
28 * New code should continue to include this file (#include <android/sync.h>)
29 * instead of ndk/sync.h so the eventual rename is seamless, but should only
30 * use the things declared in ndk/sync.h.
31 *
32 * This file used to be called sync/sync.h, but we renamed to that both the
33 * platform and NDK call it android/sync.h. A symlink from the old name to this
34 * one exists temporarily to avoid having to change all sync clients
35 * simultaneously. It will be removed when they've been updated, and probably
36 * after this change has been delivered to AOSP so that integrations don't
37 * break builds.
