DESCRIPTION

       vhangup()  simulates  a  hangup  on  the  current terminal.  This call arranges for other users to have a
       “clean” terminal at login time.

ERRORS

       EPERM  The  calling  process  has  insufficient  privilege  to  call  vhangup();  the  CAP_SYS_TTY_CONFIG
              capability is required.

CONFORMING TO

       This call is Linux-specific, and should not be used in programs intended to be portable.
