问题描述
在Windows中是否可以在进程(地址空间不同)之间传递套接字?
Is there a way to pass a socket between processes (not same address space) in Windows?
我找到此信息共享套接字，因此相信它是可能的.
I find this info Shared Sockets, therefore believe that it is possible.
"引入了WSADuplicateSocket函数以启用跨进程的套接字共享" ...
"The WSADuplicateSocket function is introduced to enable socket sharing across processes"...
更多信息:在Apache的源代码(httpd-2.2.11-win32-src.zip)上使用了带有注释的api WSADuplicateSocket.
More info : at source code of Apache (httpd-2.2.11-win32-src.zip) have usage for api WSADuplicateSocket with comments.

推荐答案
请参见 WSADuplicateSocket .它有效地表明您可以使用最喜欢的进程间通信方案"将WSAPROTOCOL_INFO结构(仅仅是数据！)发送到目标.
See the Remarks section of WSADuplicateSocket. It effectively says you can use Your Favorite Interprocess Communication Scheme to send the WSAPROTOCOL_INFO structure (it's just data!) to the target.
有很多IPC方案.我可能将共享内存与 Boost :: interprocess .但是，如果目标具有窗口+消息循环，则可以使用SendMessage.或剪贴板API，就此而言(尽管有些奇怪).该机制由您选择.
There are lots of IPC schemes. I'd probably use shared memory with Boost::interprocess. But you could use SendMessage if the target has a window + message loop. Or the Clipboard API, for that matter (though somewhat weird). The mechanism is your choice.
