NAME¶vhangup - virtually hangup the current terminal
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
Since glibc 2.21: _DEFAULT_SOURCE In glibc 2.19 and 2.20: _DEFAULT_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500) Up to and including glibc 2.19: _BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)
DESCRIPTION¶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 appropriately.
- The calling process has insufficient privilege to call vhangup(); the CAP_SYS_TTY_CONFIG capability is required.
CONFORMING TO¶This call is Linux-specific, and should not be used in programs intended to be portable.
