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 to indicate the error.
ERRORS¶
- EPERM
- The calling process has insufficient privilege to call vhangup(); the CAP_SYS_TTY_CONFIG capability is required.
CONFORMING TO¶
