Builds a file identifier for a virtual node (v-node).
| Item | Description |
|---|---|
| vp | Points to the v-node that requires the file identifier. |
| fidp | Points to where to return the file identifier. |
| crp | Points to the cred structure. This structure contains data that the file system can use to validate access permission. |

The vnop_fid entry point can be called from the process environment only.
