Subject: [PATCH v6 7/8] environment: make `getenv_safe()` a public function
Date: Thu, 7 Jan 2021 07:37:14 +0100
Message-ID: <cade8fb12f125ac8c17c448b4db2d4a6197cdc29.1610001187.git.ps@pks.im> (raw)
In-Reply-To: <cover.1610001187.git.ps@pks.im>

The `getenv_safe()` helper function helps to safely retrieve multiple
environment values without the need to depend on platform-specific
behaviour for the return value's lifetime. We'll make use of this
function in a following patch, so let's make it available by making it
non-static and adding a declaration.
