vn_isdisk — checks if a vnode represents a disk
#include <sys/param.h> #include <sys/vnode.h> int vn_isdisk(struct vnode *vp, int *errp);
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 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.
If the vnode represents a disk, 1 is returned; otherwise, 0 is returned and errp will contain the error number.
