getEnv package:gi-glib
Returns the value of an environment variable.
On UNIX, the name and value are byte strings which might or might not
be in some consistent character set and encoding. On Windows, they are
in UTF-8. On Windows, in case the environment variable's value
contains references to other environment variables, they are expanded.
Gets the list of environment variables for the current process.
The list is
Nothing terminated and each item in the list is of
the form 'NAME=VALUE'.
This is equivalent to direct access to the 'environ' global variable,
except portable.
The return value is freshly allocated and it should be freed with
strfreev when it is no longer needed.
