MOUNT(2)                      System Calls Manual                     MOUNT(2)

NAME
       mount, umount - mount or umount a file system

SYNOPSIS
       #include <sys/mount.h>

       int mount(char *special, char *name, int mountflags, char *type, char *args)
       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.  Type is the type of the file system (e.g. "mfs"), used to pick a
       file  system  server.   If  this parameter is NULL, the default type is
       used.  Args is a string  with  arguments  passed  to  the  file  system
       server.   Their interpretation is up to the server.  This parameter may
       be NULL as well.

       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.
