You must have set + stdin to be a /dev/tty device. + + When vtchs starts, it prints the number of the + currently active console. Then, in an infinite + loop, it waits for the user to change console, + and prints the number of the newly active console + when this happens. + +RATIONALE + Sometimes you need to be able to know which + console is in the foreground, and stay up to + date on this. + +SEE ALSO + fgconsole(1), chvt(1) + |
