libc-system

libc-system provides a single cross‑platform function, system, to execute a shell command and return its exit code.

Overview

• On non‑Windows systems, it calls the C library’s system() function. The command is passed as a narrow (UTF‑8) null‑terminated C string.
• On Windows, it calls the C runtime’s _wsystem() function. The command is converted from UTF‑8 to a wide (UTF‑16) string to properly handle non‑ASCII characters.

This crate lets you execute shell commands without having to worry about platform-specific differences.

Example

use libc_system::system;

let exit_code = system("echo Hello, World!");
println!("Exit code: {}", exit_code);

Platform-specific details

• Windows: Uses _wsystem from the C runtime. The command is converted into a wide (UTF‑16) string.
• Others: Uses system from libc. The command is converted into a narrow, null‑terminated string.
