.In sys/param.h
.In sys/vnode.h int vn_isdisk "struct vnode *vp" "int *errp"
DESCRIPTION
The 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
.Vt cdevsw entry’s flags must have D_DISK set. Its 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, 1 is returned; otherwise, 0 is returned and errp will contain the error number.
