## dotenv for c

![Test status](https://github.com/Isty001/dotenv-c/workflows/Test/badge.svg)

This small package adds support for loading .env files.

Just call the `env_load` function with a valid path, that contains a file named .env,

or the path of the env file itself.

If can't be loaded, it'll return `-1`, `0` otherwise. If the second parameter is set to `true`,

already existing environment variable will be replaced with the new value.

In the file, comments can be added by starting the line with `#`.

It's also possible to nest the variables, but in that case, the used variables need be already defined.

Quotes won't be removed from the strings.
