There is no direct equivalent of that in named pipes. Such differences make it difficult to port unix socket applications from Linux to Windows and vice versa; up until now!

Build brings native support for the unix socket to Windows. In the Windows implementation of the unix socket, we have kept the name, definition and semantics of the unix socket address the same as that in Linux , to make cross-platform development easier.

There are three different addressing formats for unix sockets. The one difference noteworthy here is that the Windows unix socket implementation currently does not support the auto bind feature whereby an abstract address is auto-generated by the implementation on behalf of the user.

This is also supported on Windows unix socket implementation. Unix sockets provide a mechanism for secure communication. C ommunication over unix sockets can be secured by controlling the file or directory permissions on the pathname sockets or the parent directory. The creation of the new socket file will fail if the calling process does not has write permission on the directory where the file is being created.

Similarly, for connecting to a stream socket, the connecting process should have write permission on the socket. The same level of security is available and enforced on the Windows unix socket implementation. The way you check if your call to socket succeeded or failed varies between platforms. I've written an article about the return value of socket. You'll want to check that out to learn how to determine if the call to socket succeeded or failed.

Closing a socket on Linux or macOS uses the close function. This is because on Unix-like systems socket handles are essentially equivalent to file handles. This means that on Linux and macOS, you can generally use all of the general purpose file functions with socket handles e. On Windows, socket handles can only be used with special socket functions.

On Windows you can set some socket features with the ioctlsocket function. On Unix-like systems, you can use the fcntl or the older and not recommended ioctl function. Both platforms implement the setsockopt function. This is a tiny difference, and it won't affect most C programmers. On Linux and macOS, you can get the last socket error by simplying reading the errno global variable. Once you have the error code, you may also want a more descriptive error message. On Linux and macOS, you can use the strerror function for this, while on Windows you will want to use the FormatMessage function.

You can read about a cross-platform approach to socket error messages here. There are many other differences as well.
