Item | Description |
---|---|
vp | Points to the v-node. |
flag | Identifies the flag word from the file pointer. |
vinfo | This parameter is not used. |
crp | Points to the cred structure. This structure contains data that the file system can use to validate access permission. |
The vnop_close entry point is used by the logical file system to announce that the file associated with a given v-node is now closed. The v-node continues to remain active but will no longer receive read or write requests through the vnop_rdwr entry point.
A vnop_close entry point is called only when the use count of an associated file structure entry goes to 0 (zero).
The vnop_close entry point can be called from the process environment only.
