DESCRIPTION
ustat returns information about a mounted file system. dev is a device number identifying a device containing a mounted file system. ubuf is a pointer to a ustat structure that contains the following members:
daddr_t f_tfree; /* Total free blocks */
ino_t f_tinode;/* Number of free inodes */
char f_fname[6]; /* Filsys name */
char f_fpack[6]; /* Filsys pack name */
The last two fields, f_fname and f_fpack, are not implemented and will always be filled with null characters.
"RETURN VALUE"
On success, zero is returned and the ustat structure pointed to by ubuf will be filled in. On error, -1 is returned, and errno is set appropriately.
