mount, umount - mount or umount a file system
int mount(char *special, char *name, int flag)
int umount(char *name)
Mount() tells the system that the file system special is to be mounted on
the file name, effectively overlaying name with the file tree on special.
Name may of any type, except that if the root of special is a directory,
then name must also be a directory. Special must be a block special
file, except for loopback mounts. For loopback mounts a normal file or
directory is used for special, which must be seen as the root of a
virtual device. Flag is 0 for a read-write mount, 1 for read-only.
Umount() removes the connection between a device and a mount point, name
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.
