ipc's Introduction

IPC

IPC is a C++ library that provides inter-process communication using shared memory on Windows.
A .NET wrapper is available which allows interaction with C++ as well.

Integration with Bond is available at IPC.Bond.

Build

The library is developed and maintained with Visual Studio 2019. To get started, open the IPC.sln file and build the solution. The Boost package will automatically start downloading during the first build.

Getting Started

Start with examples, C++ and C# tests.

ipc's Issues

[native] Explicitly use duration::zero() instead of {}

Using std::chrono::duration{} may not produce the same value as std::chrono::duration::zero() if duration_values is specialized.

warnings from visual studio code analysis

visual studio now integrates clang-tidy, here's the output of a run on the calc-native project. Some of these might be worth cleaning up. I didn't see any that I though were dormant bugs though.

Other OS Support

It would be more beneficial if a wide range of OSs were supported.

Can you provide examples of C++ and C#?

Can you provide examples of C++ and C#?The test is too simpler，i don't know how to use it

[native] Make the native part cross-platform

There are several components that have Windows-specific implementation (e.g. thread pool, named events) which can be expanded with corresponding cross-platform versions.

[general] Documentation is missing

There should be at least some explanation of key concepts and workflow before lookinng into unit tests makes sense.

Setup CI builds

AppVeyor and Travis

[managed] Add other containers

Currently only IVector is available. Would be good to add other containers such as list, set, map etc.

[general] Add support for streaming

vcpkg

Is there vcpkg for this library ?

Failed to send request: broken promise

Just testing with the included CalcNative example.

Running it normally works but trying to simulate a request that would take longer to process on the server side (In this case adding a sleep of 10 seconds) causes the client to fail with "Failed to send request: broken promise".

Is there some sort of timeout setting or is this an issue?

At this point, most of them can be replaced by standards such as c++17.

The internal code is well written, but the usability is not the best.

How do you think?
