- MOUNT(2) Minix Programmer's Manual MOUNT(2)
- NAME
- mount, umount - mount or umount a file system
- SYNOPSIS
- #include <unistd.h>
- #include <sys/mount.h>
- int mount(char *special, char *name, int flag)
- int umount(char *name)
- DESCRIPTION
- 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.
- SEE ALSO
- mount(1), umount(1).
