ttysrch - Lists absolute path names for tty name searches
The ttysrch file contains a list of absolute path names. This list is used
by the ttyname(3) system call to resolve tty names that are not contained
in the /dev directory.
Each entry in the ttysrch file has the following format:
xxx A directory name. Due to display constraints of certain commands
(for example, rusers) a three-character name is recommended.
N A number, which is the name of the tty special file. The
ttyname(3) system call assumes the number matches the minor
number of the dev_t associated with the tty special file.
Comments lines are delineated by a # in column 1.
System calls: ttyname(3)
