Get fd or handle from socket object
I want to create a native (c++) module for node.js which is able to send sockets to another node process, which is completely unrelated to the current process. To do so, I tought of using the ancillary library, which has a really, really easy API for this. The problem I have to solve now is how I can get the fd or the handle of a socket object of node.js.
There's a TCPWrap class in
tcp_wrap.h, which has a property called
handle_, which holds a
uv_tcp_t object from libuv, but that property is private. Also I can't #include because it's just a module of node.js an not directly in node.js itself. I don't know if it's a good idea to copy the source files to my module just to get the that class...
Have you any ides how I could do it?
I doesn't have to run on winows, tough.
I finally found a way to do it. You can find the node module here: https://github.com/VanCoding/node-ancillary
I've just taken the headers "tcp_wrap.h","stream_wrap.h" and "handle_wrap.h" and then included "tcp_wrap.h".
I could then get the object the following way:
TCPWrap* wrap = static_cast
(args->ToObject()->GetPointerFromInternalField(0)); StreamWrap* s = (StreamWrap*)wrap;
The following code then gives access to the file descriptor
