NAME
vn_isdisk – checks if a vnode represents a disk
SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
bool
vn_isdisk(struct vnode *vp);
bool
vn_isdisk_error(struct vnode *vp, int *errp);
DESCRIPTION
The vn_isdisk() and vn_isdisk_error() functions check to see if vp represents a disk. In order for vp to be a disk, it must be a character device, v_rdev must be valid, and the cdevsw entry's flags must have D_DISK set.
The arguments are:
- vp
-
The vnode to check.
- errp
-
An integer pointer to store the error number in if the call fails.
RETURN VALUES
If the vnode represents a disk, true is returned; otherwise, false is returned and errp will contain the error number.
