From 57fa1d094cd2c5ac68970526ad0a0754c548e75d Mon Sep 17 00:00:00 2001 From: Tom Gundersen Date: Wed, 1 Apr 2015 13:50:31 +0200 Subject: libsystemd: add sd-device library This provides equivalent functionality to libudev-device, but in the systemd style. The public API only caters to creating sd_device objects from for devices that already exist in /sys, there is no support for listening for monitoring events or creating devices received over the udev netlink protocol. The private API contains the necessary functionality to make sd-device a drop-in replacement for libudev-device, but which we would not otherwise want to export. --- src/libsystemd/sd-device/device-private.h | 63 +++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 src/libsystemd/sd-device/device-private.h (limited to 'src/libsystemd/sd-device/device-private.h') diff --git a/src/libsystemd/sd-device/device-private.h b/src/libsystemd/sd-device/device-private.h new file mode 100644 index 0000000000..7c6219ca6c --- /dev/null +++ b/src/libsystemd/sd-device/device-private.h @@ -0,0 +1,63 @@ +/*-*- Mode: C; c-basic-offset: 8; indent-tabs-mode: nil -*-*/ + +#pragma once + +/*** + This file is part of systemd. + + Copyright 2014 Tom Gundersen + + systemd is free software; you can redistribute it and/or modify it + under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation; either version 2.1 of the License, or + (at your option) any later version. + + systemd is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
