A single-header C/C++ library for launching and interacting with subprocesses across Linux, macOS, and Windows. It provides APIs to spawn processes, pipe stdin/stdout/stderr, and wait for completion.

Use cases

• launch a child process from C or C++
• run an external command and capture its output
• pipe data to a subprocess's stdin
• cross-platform process spawning without platform-specific code
• embed process execution in a single-header dependency

When to choose

• you need a lightweight, dependency-free way to spawn processes in C/C++
• you need cross-platform subprocess support on Linux, macOS, and Windows
• you want to avoid pulling in large frameworks like Boost.Process

When to avoid

• you need advanced features like process groups, signals, or async I/O multiplexing
• you are working in a language with built-in subprocess support
• you need shell-style piping between multiple processes
