       set appropriately.

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

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