Name
       vhangup - virtually hang up the current control terminal

Syntax
       void vhangup()

Description
       The  system call initializes a terminal line.  For example, the command
       uses to ensure that the previous user's	processes  cannot  access  the
       terminal anymore.

       First,  searches the system tables for references to the current termi‐
       nal (the control terminal of the invoking process) and  revokes	access
       permissions on each instance of the terminal that it finds.

       The  system  call  also removes all references to the inode that corre‐
       sponds to the control terminal.	The system call then invokes the  ker‐
       nel's  device close routine to turn the terminal off.  Finally, sends a
       hangup signal (SIGHUP) to the process group of  the  control  terminal.
       For further information, see for a description of process groups.

       When finishes, a terminal line is initialized; no other processes refer
       to this line.  The only way for other processes to access  the  control
       terminal is through the special file, All other requests will yield I/O
       errors (EBADF).
