NAMEvhangup - virtually hangup the current tty
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
DESCRIPTIONvhangup() simulates a hangup on the current terminal. This call arranges for other users to have a ``clean'' tty at login time.
RETURN VALUEOn success, zero is returned. On error, -1 is returned, and errno is set appropriately.
- The calling process has insufficient privilege to call vhangup(); the CAP_SYS_TTY_CONFIG capability is required.
CONFORMING TOThis call is Linux-specific, and should not be used in programs intended to be portable.
