Synopsis

     #include <mnttab.h>

Description

     The mnttab file  contains a table of  devices, mounted by
     the mount command.   Each mnttab file entry  has the fol-
     lowing structure:

          struct  mnttab {
              char  mt_dev[100];
              char  mt_filsys[100];
              short  mt_ro_flg;
              time_t  mt_time;
           };

     The fields indicate the following:

     mt_dev     The  null-padded name  of the  mounted special
                file.

     mt_filsys  The null-padded name  of the mounted-on direc-
                tory.

     mt_ro_flg  This  flag indicates  if  the  file system  is
                mounted read only.  A value other than 0 indi-
                cates the file system is mounted read only.

     mt_time    The time the file system was mounted.

     The mountab  parameter, which is defined while the system
     is being customized, determines  the number of simultane-
     ously  mounted file  systems  and  therefore the  maximum
     number of  entries in the /etc/mnttab  file.  This param-
     eter  changes when  the mountab  parameter in  the master
     file changes.
