NAMEvn_isdisk — checks if a vnode represents a disk
SYNOPSIS#include < sys/param.h>
#include < sys/vnode.h>
vn_isdisk( struct vnode *vp, int *errp);
DESCRIPTIONThe vn_isdisk() function checks 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.
Its arguments are:
- The vnode to check.
- An integer pointer to store the error number in if the call fails.
RETURN VALUESIf the vnode represents a disk, 1 is returned; otherwise, 0 is returned and errp will contain the error number.
