     DESCRIPTION
     DESCRIPTION
          Mount requests that a removable file system contained on the
          block special file identified by spec be mounted on the
          directory identified by dir .  Spec and dir are pointers to
          path names.

          Upon successful completion, references to the file dir will
          refer to the root directory on the mounted file system.

          The low-order bit of rwflag is used to control write
          permission on the mounted file system; if 1 , writing is
          forbidden, otherwise writing is permitted according to
          individual file accessibility.

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

               Any of the named files does not exist.  [ENOENT]

               A component of a path prefix is not a directory.
               [ENOTDIR]

               Spec is not a block special device.  [ENOTBLK]

               The device associated with spec does not exist.
               [ENXIO]

               Dir is not a directory.  [ENOTDIR]

               Spec or dir points outside the process's allocated
               address space.  [EFAULT]

               Dir is currently mounted on, is someone's current
               working directory or is otherwise busy.  [EBUSY]

               The device associated with spec is currently mounted.
               [EBUSY]

          Upon successful completion a value of 0 is returned.
          Otherwise, a value of -1 is returned and errno is set to
          indicate the error.

          207, it can be unmounted only using the umount kernel call.
          The unmount and mount commands described in chapter one of
          this manual will be unaware of the existence of a file
          system mounted via the mount kernel call.  The unmount
          command will be unable to unmount any file system mounted
          via using the mount kernel call directly.  Also, HP 207 file
          system utilities will not be able to properly deal with file
          systems mounted with the mount kernel call.
