 mnttab(4)                                                         mnttab(4)

 NAME    [Toc]    [Back]
      mnttab - mounted file system table

 SYNOPSIS    [Toc]    [Back]
      #include <mntent.h>

 DESCRIPTION    [Toc]    [Back]
      mnttab resides in directory /etc and contains a table of devices
      mounted by the mount command (see mount(1M)).  The file contains a
      line of information for each mounted filesystem which is structurally
      identical to the contents of /etc/fstab described by fstab(4).

      There are a number of lines of the form:

           special_file_name   dir   type   opts   freq   passno   mount_time

      consisting of entries similar to:

           /dev/dsk/c0d0s0  /  hfs  rw  0  1  537851723

      /etc/mnttab is accessed by programs that use getmntent() (see
      getmntent(3X)), It should never be manually edited, nor should setmnt
      ever be used to create invalid entries in /etc/mnttab (see

      mount_time contains the time the file system was mounted using mount.
      Its value is the number of seconds since the Epoch (00:00:00
      Coordinated Universal Time, January 1, 1970 (see time(2).

      mount and umount update the mnttab file whenever a file system is
      mounted or unmounted.  syncer rewrites the mnttab file if it is out of
      date with the mounted file system table maintained internally by the
      HP-UX kernel, (see syncer(1M)).

 WARNINGS    [Toc]    [Back]
      The table is provided only as a means for programs to return
      information about mounted file systems.

      /etc/mnttab should never be manually edited.  Any manual changes made
      to /etc/mnttab are overwritten without warning by syncer, mount, and
