     DESCRIPTION
          Ustat returns information about a mounted file system.   Dev
          is a device number identifying a device containing a mounted
          file system.  Buf is a pointer to a ustat structure (defined
          in ustat.h) that includes the following elements:

               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 */
               int     f_blksize;       /* Block size */

          Ustat will fail if one or more of the following are true:

               Dev is not the device number of a device  containing  a
               mounted file system.  [EINVAL]

               Buf points  outside  the  process's  allocated  address
               space.  [EFAULT]

          Upon successful  completion,  a  value  of  0  is  returned.

          indicate the error.
