       NAME
             ttymap - install and update /var/adm/ttymap.data based on /dev
             and /etc/ttysrch

       SYNOPSIS
             ttymap

       DESCRIPTION
             The ttymap command creates and updates /var/adm/ttymap.data
             with information from the /dev directory tree and the
             /etc/ttysrch file.

             The ttymap command is run during system initialization to
             create the /var/adm/ttymap.data file.  The
             /var/adm/ttymap.data file is used by the ttyname library
             function to search for terminal and terminal-related device
             files.  The command populates /var/adm/ttymap.data with a list
             of device files indexed by device ID and file system ID, and
             with a time-stamped map of directories within /dev.

             The ttyname(3C) library function attempts to find devices by
             lookup based on device number and file system ID.  If a
             candidate with matching device and file system IDs is found,
             ttyname checks its inode number.  If no match is found,
             ttyname checks each directory in the map to see if it is newer
             than the time stamp in the /var/adm/ttymap.data file.  If a
             newer directory is found, ttyname searches the directory for
             device files and recursively searches any newer
             subdirectories.

             The /etc/ttysrch file can be used to specify directories that
             should be ignored, which decreases the size of the
             /var/adm/ttymap.data file, providing faster lookup, and to
             specify directories that contain clone devices, which allows
             ttyname to accept device files that do not match on inode
             number.

       FILES
             /dev/*
             /etc/ttysrch
