#include <unistd.h>

int vhangup(void);

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

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

EPERM	The user is not the super-user.

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