Closes a file associated with a v-node (virtual node).
int vn_close (vp, flag, vinfo, crp) struct vnode *vp; int flag; caddr_t vinfo; struct ucred *crp;
The vn_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 vn_rdwr entry point.
A vn_close entry point is called only when the use count of an associated file structure entry goes to 0 (zero).
Note: The v-node is held over the duration of the vn_close entry point.
The vn_close entry point can be called from the process environment only.
| 0 | Indicates success. |
Nonzero return values are returned from the /usr/include/sys/errno.h file to indicate failure.
Note: The vn_close entry point may fail and an error will be returned to the application. However, the v-node is considered closed.
The close subroutine.
The vn_open entry point, vn_rele entry point.
