写成daemon程序，发现ubuntu里面的这个气泡提示很好，就网上淘了些资料，现在整理出来。
ubuntu的气泡提示是使用notify-osd来实现的，我们需要下载libnotify，
apt-get install notify-osd (ubuntu 已经自带）
apt-get install libnotify-dev
其实shell里面也可发送气泡提示，命令为notify-send，需要安装libnotify-bin
apt-get install libnotify-bin
usage:
notify-send Test “Hello World”
notify-send “Message Title” “The message body is shown here” -i /usr/share/pixmaps/apple-green.png -t 1000
ps:icon can be a png, xpm or jpg file
截图来看看：
C语言中，我们使用的是notify库，可查阅官方资料
Libnotify Reference Manual：
http://library.gnome.org/devel/libnotify/0.7/
一定要习惯阅读英文manual.多点看，慢慢就习惯了
我自己写的一个C文件：
[c-sharp] view plaincopy
[list=1]

测试一下函数：
[c-sharp] view plaincopy
[list=1]

[]{

效果还可以，正常显示，就是那个时间设置没起作用，每次都是系统默认的，这个气泡提示用于偶尔的消息通知挺好的，但是一定不能连续使用，因为这个冒泡显示是延时一点时间的，不能马上显示出下一条消息，必须等上一条消息淡化退出后才能显示下一条消息，这或许也算是一个bug吧
以下是我程序运行的效果
