About:
Reproc is a cross-platform C99/C++11 library designed for process creation and management. It provides a robust API for spawning child processes, redirecting their standard input/output/error streams, and terminating them reliably. Its primary value proposition is abstracting away the complexities of platform-specific process APIs, ensuring consistent behavior across Windows, macOS, and Linux.

Key Features:

Cross-platform (Windows, Linux, macOS)
Stream redirection (stdin, stdout, stderr)
Timeout-based operations and process termination
C99 and C++11 APIs
No external dependencies

Use Cases:

Embedding a child process runner in C/C++ applications
Building CLI tools that need to execute and manage other commands
Automated testing frameworks requiring process control

Alternatives:

libuv – Libuv is a larger event loop library that includes process spawning, whereas reproc is a focused, lightweight library specifically for process management.
Boost.Process – Boost.Process is a C++-only solution with heavy dependencies, while reproc offers a lightweight C API with no dependencies.
