--> #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 calling process has insufficient privilege to call vhangup(); the CAP_SYS_TTY_CONFIG capability is required.

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