TestPipe | Automated Test Framework | Test Automation library

I'm looking in to using third party libraries for IPC communication using named pipes on Windows. I've been using the Win32 API for this for the last few years. I was interested in replacing my implementation with a tried and true open source library.

I noticed that boost::process has an implementation of an async_pipe which would allow me to use it with boost::asio which would be really helpful for my application.

What I'm trying to do is create the named pipe on the server, which is a C# application. Once the pipe has been created, connect to it with a client using the boost::process::async_pipe.

The problem I'm having is I don't see an API in boost::process that would allow me to connect with an already created named pipe. The constructors for async_pipe create the pipe instead of connecting to an already created pipe.

Below is the code I'm currently using in the client which is erroneously creating the pipe

I have 2 executables, one in C and one in C# and want them to communicate via a named pipe.
The C# app waits for a connection but never gets one
The C app attempts to create a pipe but always gets ERROR_PIPE_BUSY
I'm obviously doing something wrong but cannot see it.

In PowerShell, I'm attempting to start a process, and wait until either the process exits, or the script gets a signal from a named pipe. While the named pipe components work fine, the code is failing to process events when the script is blocked. Here's an example of just the event-related code:

I'm trying to create a NamedPipeServerStream but when I create them I got a

UnauthorizedAccessException

And the problem is that I'm in .Net Standard so there is no constructor with PipeSecurity. Any idea of how to solve this? Do you have to add something in the UWP manifest?

I'm in .Net Standard 2.0 because the DLL are then used in a Universal App

The .Net Standard code :

I want to run a game server inside my Ubuntu machine. I want to run it in the background and write the live output of that process inside a log file. I tried using nohup and running the game server using "&" at the end but I couldn't make it work the way I wanted.

Then I started reading about named pipes and actually gave it a go. I made a simple script that in theory should work. But, of course I am missing something.

First, I made a pipe using the mkfifo command.

I am working on a custom powershell statusline, and implemented a couple cool features: battery monitoring, wifi monitoring, etc. Unfortunately, these tend to be slow to update, as they require calls to Get-NetAdapterStatistics, getting wmi objects, and other very slow calls. I am trying to spawn child processes via start-job to allow for background polling and updating a shared variable, but can't figure out how to do this. The best possible substitute I have found is a sort of IPC (as described here: Pipelining between two SEPARATE Powershell processes), but I'd prefer to stick with a traditional shared variable if possible. Is there a way to do this? The best alternative I've found is passing variables as arguments, but this won't allow for polling.

To disclaim, I am aware this is not really what powershell is designed for, but I am still wondering if this is possible. Or is the best option to write a c/c++ binary that will return the statusline? Write to a file (this seems like it might be slow)? Let me know what might work, if you are able, or if you need more information. Thank you.

I'm trying to start a child process in .NET and redirect its output to a named pipe. Attempts to write to stdout in the child process should block until a client actually reads from the named pipe.

Here is my code:
