std::realpath

resolves the specified pathname

Parameter

path: the path to resolve

Result

resolved_path: the resolved path

Description

On success the resolved path is returned, on failure an appropriate error-object is returned.

In the resolved path, symbolic links are followed and resolved. Additionally the resolved path is canonicalized. This means that the resolved path is normalized according to the local file system. Especially, redundant slashes are removed or relative paths are resolved.

realpath! $resolved_path "//var/log//../lock" println! resolved_path

Output

/run/lock
