cygwin 支持IPC http://hi.baidu.com/wangzhiqing999/blog/item/3cfe34c6587abe060ef47794.html

假如要编写 IPC 的程序， 那么首先需要再去运行那个 setup 程序。
在 Admin 的选项下面， 选择安装  cygrunsrv: NT/W2K service initiator.

然后运行 cygwin  ( Win 7 下面，需要以“管理员身份”运行 cygwin)

然后进入 /usr/bin 目录下，运行  cygserver-config

/usr/bin
$ cygserver-config
Overwrite existing /etc/cygserver.conf file? (yes/no) yes
Generating /etc/cygserver.conf file

Warning: The following function requires administrator privileges!

Do you want to install cygserver as service?
(Say "no" if it's already installed as service) (yes/no) yes

The service has been installed under LocalSystem account.
To start it, call `net start cygserver' or `cygrunsrv -S cygserver'.

Further configuration options are available by editing the configuration
file /etc/cygserver.conf.  Please read the inline information in that
file carefully. The best option for the start is to just leave it alone.

Basic Cygserver configuration finished. Have fun!

 

----- 在 ipc 服务没有启动的情况下， 运行 ipcs ， 结果会提示 “Bad system call”

/usr/bin
$ ipcs
Bad system call

 

----- 运行 cygrunsrv -S cygserver  来启动服务.

/usr/bin
$ cygrunsrv -S cygserver

-- 再次查看 ipcs， 不抱   “Bad system call”  错了.

/usr/bin
$ ipcs
Message Queues:
T     ID               KEY        MODE       OWNER    GROUP

Shared Memory:
T     ID               KEY        MODE       OWNER    GROUP

Semaphores:
T     ID               KEY        MODE       OWNER    GROUP

这样就可以开始编写 / 运行  ipc 的相关 C 程序了。
