Fixes #71 /cc @capri-xiyue |
This fixes a bug where a pointer was initialized, but to the zero value. Like a *bool initialized to &false. Previously this would be considered "unset" because false is the zero value for a boolean. Now envconfig considers whether the pointer was initialized first, before checking whether the value is zero.
