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.
