vhangup - virtually hangup the current tty
#include <unistd.h> |
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.
Tag | Description |
---|---|
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.
