vhangup: doslova zavěšení současného tty

Originální popis anglicky: vhangup - virtually hangup the current tty

Návod, kniha: Linux Programmer's Manual

STRUČNĚ

#include <unistd.h> int vhangup(void);

POPIS / INSTRUKCE

vhangup simulates a hangup on the current terminal. This call arranges for other users to have a “clean” tty at login time.

NÁVRATOVÁ HODNOTA

On success, zero is returned. On error, -1 is returned, and errno is set appropriately.

CHYBY / ERRORY

EPERM

The calling process has insufficient privilege to call vhangup; the CAP_SYS_TTY_CONFIG capability is required.

ODPOVÍDAJÍCÍ

This call is Linux-specific, and should not be used in programs intended to be portable.
