POSIX IPC Utilities

IPC Wrappers for POSIX Message Queues, Shared Memory, and Pipes

This repository contains C++ wrappers for POSIX Message Queues, Shared Memory, and Pipes, providing a convenient interface for inter-process communication (IPC) in non-blocking mode. The implementation includes support for generic data types using C++ templates.

Overview

POSIX Message Queues

The NonBlockingMQ class provides a non-blocking interface for POSIX Message Queues, allowing for sending and receiving messages of any data type.

POSIX Shared Memory

The NonBlockingSHM class provides a non-blocking interface for POSIX Shared Memory, enabling processes to share data efficiently.

Pipes

The NonBlockingPipe class provides a non-blocking interface for named pipes (FIFO), supporting generic data transport.

UNIX Domain Sockets

The NonBlockingUnixSocket class provides a non-blocking interface for UNIX domain sockets, allowing for inter-process communication on the same machine.

Prerequisites

• C++ compiler supporting C++11 or later
• POSIX-compliant operating system (Linux, macOS, etc.)
• Bazel build system

Getting Started

Building the Project

Ensure Bazel is installed on your system. You can download and install Bazel from the Bazel website.
