vhangup ? virtually hangup the current tty |
#include <unistd.h> int vhangup(void); |
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. |
EPERM |
The user is not the super-user. |
This call is Linux-specific, and should not be used in programs intended to be portable. |
