      NAME
           mnttab - mounted file system table

      SYNTAX
           #include <mnttab.h>

      DESCRIPTION
           Mnttab resides in directory /etc and contains a table of
           devices, mounted by the mount(1) command, in the following
           structure as defined by <mnttab.h>:

                struct    mnttab {
                     char mt_dev[10];
                     char mt_filsys[10];
                     short     mt_ro_flg;
                     time_t    mt_time;
                };

           Each entry is 26 bytes in length; the first 10 bytes are the
           null-padded name of the place where the special file is
           mounted; the next 10 bytes represent the null-padded root
           name of the mounted special file; the remaining 6 bytes
           contain the mounted special file's read/write permissions
           and the date on which it was mounted.

           The maximum number of entries in mnttab is based on the
           system parameter NMOUNT located in /usr/src/uts/cf/conf.c,
           which defines the number of allowable mounted special files.
