Comment (by leif):
You may also simply wrap `getenv()` with an additional (preferably `const
char*`) default parameter, returned if the environment variable isn't set,
just like Python's `os.environ.get("VAR_NAME", default_value)`.
(And the additional parameter might itself default to either `""` or
`NULL`. But if you provide a default parameter for your wrapper function,
you won't be able to just overload `getenv()`. So it would be best to add
a `getenv()` function with an additional ''non-optional'' parameter, then
calling `getenv(NON_DEFINED_NAME)` would just return `NULL`, while
`getenv(NON_DEFINED_NAME, DEFAULT_VALUE)` would return `DEFAULT_VALUE`,
"transparently".)
