.env Loader Library

Introduction

This library provides a simple loader for .env files, allowing you to read key/value pairs, query them, and optionally inject them into the process environment.

Usage

1. Call env_load("path/to/.env") to load environment variables.
2. Use env_get("KEY") to retrieve values.
3. Optionally, call env_inject_all(1) to inject variables into the system environment.
4. Free memory with env_free().
