I'm trying to give an already running child process access to a socket I'm using in the parent process. This must be done in C/C++ and on Windows and Linux. Currently I only know of Unix domain sockets for sending the socket's file descriptor to the child process which is perfectly suitable but only works on Linux. But I haven't found a solution that works on both platforms yet.

    Have you looked at Boost? http://www.boost.org/ – Nick Feb 14 '14 at 09:16
  • I looked at it briefly but I couldn't find a hint whether it is able to send TCP sockets on windows. Do you know if this is possible? – HardcorEViruS Feb 14 '14 at 09:18

    Your title is too broad. "IPC" = "InterProcess Communication", and also includes shared memory, pipes and other things. What you want is just a network library. You should check Boost.Asio. – Synxis Feb 14 '14 at 09:19

  • Have you tried D-bus, it is Linux and Windows – Brandin Feb 14 '14 at 09:21
  • @Brandin I'm currently using D-bus with Qt and I don't really need Qt for this but I couldn't find whether D-Bus for windows can send sockets. – HardcorEViruS Feb 14 '14 at 09:22
  • @Synxis As it seemd Boost.Asio can only send sockets over Unix Domain Sockets which doesn't work on windows – HardcorEViruS Feb 14 '14 at 09:24

    Boost.Asio works perfectly fine on Windows. – Synxis Feb 14 '14 at 09:27
  • @HardcorEViruS It sounds like you need a network library like others mentioned. For a simple solution you could look at Apache Portable Runtime it has network IO socket functions – Brandin Feb 14 '14 at 09:28
  • ZeroMQ might be another contender http://zeromq.org/ – Nick Feb 14 '14 at 09:32
  • @Nick As per [this Answer](http://stackoverflow.com/a/15670098/2560791) ZeroMQ doesn't have the capabilities to send sockets at least on windows – HardcorEViruS Feb 14 '14 at 09:44
  • @Synxis Boost.Asio seems to only be able to send socket file descriptors on Linux using Unix Domain Sockets but not on Windows – HardcorEViruS Feb 14 '14 at 09:45
  • @HardcorEViruS I see you've changed your question - it wasn't clear originally what you were trying to do. I've flagged it for reopening but you'll need more voters. Alternatively ask a new question. – Nick Feb 14 '14 at 09:59
  • I agree with Nick, I voted to reopen it. – Synxis Feb 14 '14 at 10:59
  • Look at `WSADuplicateSocket`. – n. m. could be an AI Feb 14 '14 at 11:30
