# vcpkg_backup_restore_env_vars
|
||
|
|
|
||
|
|
The latest version of this document lives in the [vcpkg repo](https://github.com/Microsoft/vcpkg/blob/master/docs/maintainers/vcpkg_backup_restore_env_vars.md).
|
||
|
|
|
||
|
|
Backup or restore the environment variables
|
||
|
|
|
||
|
|
## Usage:
|
||
|
|
```cmake
|
||
|
|
vcpkg_backup_env_variables(VARS [<environment-variable>...])
|
||
|
|
vcpkg_restore_env_variables(VARS [<environment-variable>...])
|
||
|
|
```
|
||
|
|
|
||
|
|
### VARS
|
||
|
|
The variables to back up or restore.
|
||
|
|
These are placed in the parent scope, so you must backup and restore
|
||
|
|
from the same scope.
|
||
|
|
|
||
|
|
## Notes
|
||
|
|
One must always call `vcpkg_backup_env_variables` before
|
||
|
|
`vcpkg_restore_env_variables`; however, `vcpkg_restore_env_variables`
|
||
|
|
does not change the back up variables, and so you may call `restore`
|
||
|
|
multiple times for one `backup`.
