raxvan / subprocess

Subprocess Library for C++

This library offers an intuitive and effective way to interact with subprocesses in C++. It is designed to be straightforward, versatile, and easy to use, so you can control and communicate with subprocesses directly from your C++ application.

Features

• Start and manage subprocesses from within your application.
• Interact with the standard input/output/error streams of these processes.
• Synchronize and wait for subprocesses to finish.
• Capture and handle exit codes.
• Support for windows and posix platforms.
• posix_spawn instead of fork() for performance

Getting Started

To get started with the library, you should first clone the repository:

git clone https://github.com/raxvan/subprocess.git

Usage:

subprocess p;
subprocess::CreateData cd;

cd.make_shell("echo hello");

auto sout = [&](const char* buffer, const std::size_t sz) {
	std::cout << std::string(buffer, sz);
};
auto serr = [&](const char* buffer, const std::size_t sz) {
	std::cerr << std::string(buffer, sz);
};
if(p.start(cd, sout, serr))
{
	//started successfully

	int rc = p.join();
	std::cout << "process terminated with " << rc << std::endl;
}
else
{
	std::cerr << "failed to start process!" << std::endl
}

Implementation: You can either include src/subprocess.cpp in a cpp file or add it to your project
