It does not free the disk* structure. The `ufs_disk_fillout` and `ufs_disk_fillout_blank` functions open a disk specified by name and populate the structure pointed to by disk. The disk is opened read-only. The specified name may be either a mountpoint, or a device name. The `ufs_disk_fillout` function assumes there is a valid superblock and will fail if not, whereas the `ufs_disk_fillout_blank` function makes no assumptions of that sort. The `ufs_disk_write` function attempts to re-open a disk as writable if it is not currently. ERRORS The function `ufs_disk_close` has no failure points. The function `ufs_disk_fillout` may fail for any of the reasons `ufs_disk_fillout_blank` might, as well as for any reason sbread(3) might. The `ufs_disk_fillout_blank` may fail and set errno for any of the errors specified for the library functions open(2), strdup(3). Additionally, it may follow the libufs(3) error methodologies in situations where no device could be found to open. The function `ufs_disk_write` may fail and set errno for any of the errors specified for the library functions open(2) and stat(2). Namely, it will fail if the disk in question may not be written to.
