vhangup - virtually hangup the current terminal
SYNOPSIS¶
#include <unistd.h>
int vhangup(void);

vhangup(): _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.
ERRORS¶
- EPERM
- 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.
