<H2>DESCRIPTION</H2><PRE>
|
|
<STRONG>Mount()</STRONG> tells the system that the file system <EM>special</EM> is to be mounted on
|
|
the file <EM>name</EM>, effectively overlaying <EM>name</EM> with the file tree on <EM>special</EM>.
|
|
<EM>Name</EM> may of any type, except that if the root of <EM>special</EM> is a directory,
|
|
then <EM>name</EM> must also be a directory. <EM>Special</EM> must be a block special
|
|
file, except for loopback mounts. For loopback mounts a normal file or
|
|
directory is used for <EM>special</EM>, which must be seen as the root of a
|
|
virtual device. <EM>Flag</EM> is 0 for a read-write mount, 1 for read-only.
|
|
|
|
<STRONG>Umount()</STRONG> removes the connection between a device and a mount point, <EM>name</EM>
|
|
may refer to either of them. If more than one device is mounted on the
|
|
same mount point then unmounting at the mount point removes the last
|
|
mounted device, unmounting a device removes precisely that device. The
|
|
unmount will only succeed if none of the files on the device are in use.
|
|
|
|
Both calls may only be executed by the super-user.
