QUESTION

Windows: Check existence of named pipe

Asked 2021-Mar-24 at 18:08

I am writing a C++ program that makes use of named pipes on Windows. I can create and work with them quite fine. The only piece missing to the puzzle is a function to check for a pipe's existence.

Coming from the Unix world I originally tried std::filesystem::exists("\\\\.\\pipe\\myPipe") but this is not reliable and often errors with ERROR_PIPE_BUSY.

While searching for an alternative way to check for a pipe's existence, I stumbled upon this issue on GitHub (Boost process) and from there I take it that Boos process circumvents the problem by using a special naming scheme and a counter and then keeping track of that internally (only seems to work for pipes created via Boost process though).

Furthermore according to How can I get a list of all open named pipes in Windows? it seems that there are ways to list the existing named pipes. These solutions are not using C++ though and I did not find a way to port that over.

After having read the documentation of CreateNamedPipe, I now assembled the following solution to my problem:

std::filesystem::exists("\\\\.\\pipe\\myPipe") returning ERROR_PIPE_BUSY means it is using CreateFile() to actually connect to the pipe. It is not unreasonable for an exists() implementation to attempt to open the requested file to check its existance.

Per the CreateFile() documentation:

If there is at least one active pipe instance but there are no available listener pipes on the server, which means all pipe instances are currently connected, CreateFile fails with ERROR_PIPE_BUSY.

Which means the pipe does technically exist, it is not ready to receive a new client at that moment.

In the link you provided, many of the solutions provided suggest using .NET's System.IO.Directory.GetFiles() method to iterate though the contents of "\\.\pipe\". This answer shows how that call translates into Win32 API calls using FindFirstFile() and FindNextFile(). You can easily do the same API calls in C++, eg:

It turns out that it is possible to build all of Boost while using ICU for those components that support the ICU feature, as follows.

./vcpkg install boost-locale[icu] boost-regex[icu] boost --triplet x64-windows --recurse

QUESTION

How to avoid branching for a call where the number of arguments is dependent on conditionals?

Asked 2019-May-29 at 13:49

I'm converting some code from using CreateProcess to use boost-process instead. I need to replace my CreateProcess usages with boost::process::child. The problem is they have incompatible ways for me to say "I want to use the default value". What used to be a one line command has become sixteen if statements.

The function I currently use works like this (simplified):

The mistake is indeed very simple: you should cancel the deadline timer!

io_service::run() will not return unless

an exception emanated from a handler
no more work is queued.

While the dead line timer is in progress, that means the second condition isn't met. So io_service::run() waits for it because you asked it to.

Other notes:

use the error code to detect timer cancellation instead of racy time comparisons
no need to loop-chain the timer (in fact, that's asking for bugs where the io_service never completes)
your code failed to initialize stopped and killed
