       vhangup - virtually hangup the current terminal

SYNOPSIS

       #include <unistd.h>

       int vhangup(void);

       vhangup(): _BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)

DESCRIPTION

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

RETURN VALUE

       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.

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.
