# vn_getpath

Construct the path to a vnode.

## Declaration

```occ
int vn_getpath(struct vnode *vp, char *pathbuf, int *len);
```

## Parameters

- `vp`: The vnode whose path to obtain.
- `pathbuf`: Destination for pathname; should be of size MAXPATHLEN
- `len`: Destination for length of resulting path string. Result will include NULL-terminator in count--that is, "len" will be strlen(pathbuf) + 1.

## Return Value

Return Value 0 for success or an error code.

## Discussion

Discussion Paths to vnodes are not always straightforward: a file with multiple hard-links will have multiple pathnames, and it is sometimes impossible to determine a vnode's full path. vn_getpath() will not enter the filesystem.
